Three ways in: a Marketplace app, a scoped token, or an inbound webhook. Outside Stripe charges stay in Stripe until you send them across.

Our verdict
HighLevel is the pick for an agency that resells marketing to local clients and wants a CRM, funnels, email, SMS and a white-label client portal in one place. It is widely used, and the setup takes significant time. Shared email sending needs monitoring, and phone, SMS, and AI incur usage fees on top of the subscription.
You already run the ads. The open question is whether a form, a Stripe charge, or a tracker postback lands in HighLevel without a chain of Zaps. Three paths do that job. Install a Marketplace app, post JSON to an inbound workflow webhook, or call API 2.0 with a Private Integration Token or with OAuth.
Reselling a CRM to local clients uses those three paths and stops there. Paid traffic, where the ad click, the order and the affiliate postback have to share one record, is a different job. For that job, read the ElasticFunnels review before you budget an OAuth build. What follows is from HighLevel's API docs, pricing page and help articles, and from public reports by people wiring accounts.
HighLevel's developer portal points current work at an OAuth API. The live reference is the marketplace docs. The older API 1.0 reference remains at public-api.gohighlevel.com.
That v2 reference covers contacts, conversations, calendars, opportunities and payments, and it lists real-time notifications for 50+ events. Calls go to services.leadconnectorhq.com. The private integrations guide includes a Version header on the sample request, set to 2021-07-28.
A Private Integration Token is the scoped key for internal calls against one sub-account. The authorization doc puts webhooks and custom modules on the OAuth Marketplace app instead. You can create up to 20 of these tokens at the agency level and 20 at the location level.
OAuth is the right choice when other accounts need to install the integration, or when HighLevel has to push events out. Published caps are 100 requests per 10 seconds and 200,000 per day, per app, per location or per company. Each response repeats the remaining allowance in the X-RateLimit headers.
Marketplace outbound webhooks retry up to 12 times after the first attempt when the URL does not return a success status. An endpoint that stays under 90% success across 10,000 or more deliveries in three days can be paused after a warning. Builders report the event arriving before a follow-up read can see the new record, so they wait briefly and fetch again.
Advanced API access, the line that includes OAuth, is on Agency Pro. Unlimited lists Basic API access. An Enterprise account can request higher API limits. Connecting a form does not take phone, SMS, email or AI usage off the bill.
The integrations page markets 500+ business tools. You browse, install and authorize, and you do that per sub-account. That path fits when someone has already shipped the connector.
Zapier is the connector people try first for contacts. Practitioners call it thin once the job is an agency action, or a custom field on an opportunity. That is where the inbound webhook or API 2.0 takes over.
Stripe's own connect article is the source for the one-account rule in the panel above. A second brand needs its own sub-account. Payments created in Stripe before the connection are not imported. HighLevel tracks new transactions that run through it after you connect.
A charge that never touches a HighLevel order form or invoice raises no native payment trigger. People trying to move a pipeline stage from an outside Stripe payment hit that gap. The bridge is the inbound webhook, or your own API call. Attribution back to the ad click depends on the parameters you store on the form or in a custom field. The postback itself belongs on a tracker. The affiliate postback guide explains the setup.
The inbound webhook is an LC Premium Trigger. It takes JSON on POST, GET or PUT. The help article says agencies on any public plan can turn Premium Triggers on, and each sub-account then has 100 free executions. Runs past that allowance can incur an execution cost, and the agency turns rebilling on per sub-account when it does not want to absorb that cost.
A workflow that creates or updates a contact requires an email or a phone number in the payload, unless it only runs contactless actions. Practitioners report a test payload looking fine and a live run returning no value for the mapped fields.
ElasticFunnels is a funnel platform for teams that run paid traffic. It builds the pages, split-tests variants under one URL, hosts the checkout, and keeps the session, the order, the rebill and the refund on one timeline with the CRM. The ElasticFunnels homepage lists 50+ integrations across gateways, affiliate networks, ad platforms, email and CRM, and a developer platform with a CLI and an API.
Compare it with HighLevel for the job you need done. HighLevel is the agency platform: sub-accounts, white-label resale, SMS, and a CRM the client logs into. ElasticFunnels is the paid-traffic path, where a click, an order, a rebill and a refund are one record, so you are not reconciling a page tool, a checkout and a tracker to see which angle made money. ElasticFunnels vs GoHighLevel is that choice. The wider set of funnel platforms is on the funnel builder alternatives page.
ElasticFunnels is newer than HighLevel, and there is very little independent review coverage you can check its integration claims against. Until you run real volume, you are largely taking the vendor's word for how the API and the postbacks behave. That is what you would expect from a platform launched in 2023. The pages, the checkout and the CRM are on the account to use, and ElasticFunnels' trial runs 14 days with no card required.
For that paid-traffic job, the ElasticFunnels review covers the plans and the checkout detail.
Post the form or the checkout you control to the inbound webhook. A Private Integration Token covers reads and writes on a single sub-account. Choose OAuth when HighLevel must push events, or when other accounts will install the app. That access is the Advanced API plan. When you need the sale and the ad click on one record, open the ElasticFunnels review before you pay for the OAuth build.
A workflow has stalled, billing has locked the account, or a client on a white-label login is asking you to call HighLevel. Agency admins and agency users open the blue question-mark drawer on a desktop. Location admins and location users never see that button, and HighLevel will not change the agency account unless someone with agency access is the one asking. Open the support options.
If you are locked out of the app, call +1 888-732-4197 and choose option 2, or write to billing@gohighlevel.com. The mailbox opens a ticket on its own. Product questions go through that drawer as chat, a Zoom call, or a ticket, once the drawer has the account details.
If you can log in as the parent account, open that drawer and start with chat. If you cannot log in, use the billing phone or the billing mailbox.
HighLevel's support process routes you to a different team as the account matures. During a trial, the article directs you to a kickoff call.
On a trial, start with the kickoff call. Use the call to get the account running before you rely on the general queue.
During the first 90 days as a paying customer, Customer Success is the primary support resource. Book those sessions while that team still owns the account.
After the first 90 days, Zoom, in-app live chat with an AI or an agent, and tickets are available any hour, any day. The phone line is for sales, billing, or a login problem, and every caller is checked against the parent account.
The drawer is a desktop control. A phone browser does not show it. Chat starts inside the account. When the person on chat cannot close the issue, the help article says they escalate and open a ticket so the thread continues.
Premium Support is an optional add-on once you have been on the platform for 90 days. HighLevel bills it separately from the subscription. The monthly and annual prices are in the Premium Support table further down this page. HighLevel states that the add-on cuts chat and Zoom waits from six minutes to one minute, and ticket first responses from ten hours to three hours. It also adds a technical account manager, a Slack channel, and faster routing. The vendor's Enterprise pricing page lists this add-on as included.
Buying the add-on leaves a client login without the vendor support button. If you resell a white-label account, you remain the person that client can reach. Every public plan card on the pricing page lists 24/7 Support. The add-on is extra. Tier numbers are on the HighLevel pricing breakdown.
The journey article points to the Help Center, the Academy, events, a daily Q&A, and the HighLevel Community. The community is for learning from other users. Account-specific troubleshooting stays with official support. That is the boundary the article sets.
Threads on r/gohighlevel describe support as inconsistent, with a fast chat on one inquiry and a ticket that sits unanswered on the next. One report says live chat cleared a misconfiguration in under a minute when the agent stayed on the thread. Other agency owners describe multi-week stalls and replies from agents who do not know the product. A third write-up, from the same forum, is the counterweight: an agent calmly guided the fix instead of handing it off.
My take: I would start with live chat or Zoom once Customer Success has stepped back, because the threads that end well are the ones where an agent stayed on the chat. A ticket follows the vendor's own timetable, and the threads that go badly are about tickets. A person on a client login needs the agency that owns the account.
If you have parent-account access and you can log in, open the desktop drawer and start with chat. If you cannot log in, use the billing phone or the billing mailbox.
HighLevel, still widely called GoHighLevel, is the agency platform those articles describe. HighLevel LLC in Dallas has sold it since 2018, and it is one of the larger agency platforms on the market. The downsides are specific, and they are worth knowing before you put a card down.
Think of it as an operating system for a marketing agency. It bundles a CRM and sales pipelines, a website and funnel builder, email, SMS and voice, booking calendars, reputation management, workflow automation, courses and memberships, payments and invoicing, and an affiliate manager, and it runs all of it from one login. The pitch is that you stop paying for and stitching together five or six separate tools. For an agency that manages many clients, each client sits in its own sub-account under your parent account, which is the shape most competitors do not have.
The consolidation is the honest reason to buy it. Long-term users describe the value as dropping the other subscriptions once several client accounts are running. Each module lags behind a dedicated tool in its own category. A dedicated email platform builds better emails, a fuller CRM runs a deeper pipeline, and a funnel tool builds sharper funnels. The modules are all present, they talk to each other, and one bill replaces many. The math works out when the switch lets you cancel several other tools. It rarely does when the platform replaces one tool you already like.
The second draw is resale. On the Agency Pro plan, SaaS Mode lets you rebrand the platform as your own software, set your own prices, auto-create client accounts when someone subscribes, and rebill their phone, SMS and email usage with a markup you keep. That turns the platform from a cost into a product you sell. Setting it up takes real work, and agencies run real resale businesses on it.
Two structural things also count. Every plan includes unlimited contacts and unlimited users, and sub-accounts are unlimited from the Unlimited plan up. Your software cost does not climb every time you sign a client or add a team member, which is the trap with a per-seat CRM. Because so many agencies serve the same industries, there is a deep library of snapshots and templates plus a large, active community. Once you have built an onboarding flow, you can clone it for the next client in an afternoon.
Take email deliverability seriously, because it is the complaint that costs real money. HighLevel sends mail through a shared IP pool, and users report open rates falling and messages landing in spam even after they set up SPF, DKIM and DMARC. The same pattern shows up on accounts with the authentication records set correctly, which points to the shared IP's reputation. Heavy senders end up routing through a dedicated SMTP or a dedicated IP. If your business or your client's business lives on email, send one campaign to a seed list and check inbox placement before you migrate anything important.
Reliability is the second thing to weigh. Users describe a love-hate relationship: a lot of features, and a stream of errors that stop a workflow mid-task. HighLevel's own public status page has logged repeated incidents through 2025 across workflows, forms, SMS delivery, the email builder and the Social Planner. For internal use, that is an annoyance. On a white-label resale, a broken automation becomes the client's emergency. Read the access rule above before you set a resale price.
Then there is the learning curve. The same people who recommend the platform are the first to mention it. Workflows, triggers, snapshots, calendar logic and A2P SMS registration all take time to get right, and the setup hours can quietly cancel the money you saved by consolidating, especially if you build every automation from scratch. Plan for a real setup period, or buy a proven snapshot to skip part of it.
The pricing page lists the base subscription. Phone numbers, SMS, email and premium AI are usage-based, billed on top. On the Unlimited and Agency Pro plans you can rebill those costs to clients with a markup, which turns the variable cost into margin. On the Starter plan you absorb it. Either way, model your expected sending volume, because the monthly total moves with it.
One more note on trust. A lot of the glowing HighLevel content online is written by affiliates earning a recurring commission, so a life-changing testimonial deserves a second read. The product is capable. Weigh the specific, unglamorous reports more heavily than the testimonials.
HighLevel fits an agency that resells marketing to local businesses and wants to run and, on Agency Pro, white-label the whole stack from one place. If you manage several clients, will actually retire other subscriptions, and are willing to invest the setup time, it is a defensible pick and the resale model can pay for itself. If you are a solo operator who needs one clean tool, a paid-traffic media buyer who mostly wants funnels and tracking, or a business whose whole model rides on high-volume email, the breadth is more than you need and the deliverability and reliability trade-offs land harder.
Its closest comparison on the funnel itself is ClickFunnels vs GoHighLevel. ClickFunnels is sharper at the funnel and has no agency resale or native SMS and voice. GoHighLevel vs Systeme.io is the other comparison, when the buyer wants funnels, email and courses in a smaller bundle. When the other tool only builds pages, see Leadpages vs GoHighLevel. Read the HighLevel alternatives before you commit, and the tier-by-tier numbers are on the pricing breakdown. Vendor documentation and public threads are the sources. The standard is on the methodology page.
HighLevel's public Black Friday history includes limited add-on packs, not always core plan discounts; affiliates are told to join a list for the next promo.
“This is a limited-time offer, available only from Nov 25th, 00:00 am PST – Dec 8th, 23:59 Pm PST.”
“Join the Affiliate Promo Interest List and we'll email you the moment new Affiliate Promo is confirmed.”
