Authenticate to the Forms API using your GHL API key and, where available, OAuth tokens. Keep credentials secure and rotate keys regularly to maintain a strong security posture.
Connect using your ActiveCampaign Postmark API key or OAuth method supported by the app. Protect credentials and restrict access to trusted workflows.
API Endpoint 1: GET /forms/ — Retrieve all forms. API Endpoint 2: GET /forms/submissions — Retrieve submissions for a specific form. Additional endpoints are available in the API docs and your account.
When a form is submitted in GHL, push the data to ActiveCampaign Postmark to create or update a contact and trigger a campaign.
Actions include: create or update contacts, apply tags, and enroll subscribers in automations.
POST /forms/submissions
Key fields: name, email, form_id, submission_id, and custom fields mapped to ActiveCampaign Postmark fields.
Trigger when a new submission arrives to update the contact in ActiveCampaign Postmark instantly.
Actions: upsert contact, assign to lists/segments, start automation.
POST /forms/submissions
Fields mapped: email, first_name, last_name, phone, custom fields.
Trigger after submission to add to a newsletter list or automation sequence.
POST /forms/submissions
Mapping: email, name, and related custom fields for follow-up series.
Automate lead capture and follow-up without writing code, reducing manual data entry.
Real-time data sync minimizes delays between form submissions and outreach.
Flexible mappings and scalable automations support growing contact lists and complex workflows.
This glossary defines essential terms used in the GHL Forms API integration with ActiveCampaign Postmark, including API, authentication, endpoints, webhooks, and data mapping.
Application Programming Interface: a set of rules that allows software to communicate with other software.
A webhook is a URL endpoint that receives real-time data from a service when an event occurs.
Process that verifies identity and permissions before allowing API access.
A specific URL path on an API used to perform an action or retrieve data.
Map submission data to a scoring model and trigger a tailored automation based on score.
Automatically enroll new leads into nurturing sequences and personalized emails.
Route submissions to different campaigns or teams based on form answers.
Collect your GHL Forms API key and your ActiveCampaign Postmark API key from the developer dashboards.
Map form fields to the corresponding contact fields in Postmark and set up required mappings.
Run test submissions, verify data flow, and enable the integration for production.
The Forms API integration enables you to connect GHL form submissions with ActiveCampaign Postmark to automatically create or update contacts and trigger campaigns. This no-code approach speeds up onboarding and ensures consistent data flow between tools. It also helps you scale outreach as your form submissions grow.
Authentication uses your GHL API key for the Forms API and your ActiveCampaign Postmark credentials for the app. Store keys securely, rotate regularly, and apply the principle of least privilege to your integration workflows.
The available endpoints include GET /forms/ to fetch forms and GET /forms/submissions to retrieve submissions. Your account docs provide the full endpoint catalog and any environment-specific details.
No heavy coding is required. The integration is designed for no-code builders and can be orchestrated via automation tools like Zapier App Connector or built directly in your workflow using API calls guided by the endpoint list.
Field mapping should align form fields to the corresponding contact fields in Postmark. Start with essential fields like email and name, then add custom fields as needed for segmentation and automation logic.
If submissions fail to sync, check API keys, verify endpoint access, review error messages in logs, and retry the failed submission. Ensure rate limits are not being hit and that the target fields exist in Postmark.
Support and documentation are available in your developer portal and the Rankr docs. If you need additional help, contact our support team or consult the knowledge base for step-by-step guides.
