How to connect WHMCS to the Users API

Connecting the Users API with WHMCS for seamless automation

How to connect the Users API to WHMCS

This guide walks you through authenticating, configuring endpoints, and validating data sync between WHMCS and the Users API, so you can automate tags, statistics, and reporting without code.

Authorize the Users API access

Authenticate calls to the Users API using an API key issued in GHL. Store the key securely in WHMCS settings and rotate it regularly.

Authorize WHMCS in GHL

Register WHMCS as an application in GHL, generate client credentials, and grant necessary scopes such as socialplanner/tag.readonly to enable read access to tags and analytics.

Key endpoints used in this integration

– GET /social-media-posting/:locationId/tags — fetch tags for a specific location – POST /social-media-posting/:locationId/tags/details — retrieve detailed tag information – socialplanner/statistics.readonly — read access to statistics – POST /social-media-posting/statistics — submit or refresh statistics

Top 3 connection patterns between Users API and WHMCS

1) Location tag retrieval

Trigger: when a new location is added in WHMCS or a location’s tags need refreshing.

Actions: call GET /social-media-posting/:locationId/tags to pull current tags and map them to WHMCS records.

GET /social-media-posting/:locationId/tags

locationId, authorization header, optional locationId metadata

2) Tag details and analytics sync

Trigger: on tag detail requests or scheduled sync.

Actions: POST /social-media-posting/:locationId/tags/details to get detailed tag data and push to WHMCS fields.

POST /social-media-posting/:locationId/tags/details

locationId, tagDetails payload, authorization

3) Global statistics to dashboards

Trigger: daily batch or on-demand request for metrics.

Actions: GET socialplanner/statistics.readonly and POST /social-media-posting/statistics to populate WHMCS dashboards.

socialplanner/statistics.readonly; POST /social-media-posting/statistics

dateRange, metrics, auth

No-code benefits of connecting WHMCS with the Users API

Enter endpoint URLs in WHMCS, map fields, and enable webhooks if available.

3) Test and deploy

Run tests, verify data flow, and go live after validation.

Frequently Asked Questions

Do I need to code to connect WHMCS with the Users API?

No extensive coding is required. Use WHMCS settings to input API credentials and map fields between WHMCS and the Users API. The integration relies on standard REST calls and can be set up via the WHMCS admin panel. If you prefer a no-code approach, middleware like Zapier can bridge WHMCS and GHL using the endpoints described.

Authentication is handled with API keys issued in GHL and applied in WHMCS. Store keys securely, restrict scopes, and rotate keys regularly. OAuth tokens can be used if your setup supports it, but API keys are common for this flow.

Essential endpoints include: GET /social-media-posting/:locationId/tags to fetch tags, POST /social-media-posting/:locationId/tags/details for tag details, and endpoints for statistics such as socialplanner/statistics.readonly and POST /social-media-posting/statistics to surface metrics in WHMCS.

Security centers on strong API key management: keep keys in a secure vault, limit scopes to what’s needed, monitor usage, and revoke keys if compromise is suspected. Use HTTPS for all calls and rotate credentials regularly.

Yes. You can automate tagging, tagging-based workflows, and reporting by scheduling calls to the endpoints and pushing results into WHMCS records, invoices, or dashboards. This reduces manual steps and keeps data aligned.

If you need to revoke access, remove the API keys, disable the app in GHL, and rotate any dependent credentials in WHMCS. Re-keying helps prevent unauthorized access and maintains security.
