No-code integration lets you automate data flow between MailUp and the Contacts API without writing code.
Real-time or near-time syncing reduces manual updates and data mismatches.
Reusable, template workflows let you automate campaigns and contact updates across teams.
This section defines core terms (endpoints, authentication, triggers, actions) and describes how data moves through the integration.
A URL and HTTP method used to perform a specific action in the GHL Contacts API.
An event in MailUp that starts a workflow in the integration.
A person stored in the Contacts API with fields like email, name, and status.
The process of pairing fields between MailUp and the Contacts API so data transfers correctly.
Automatically create a new contact in the Contacts API when a new MailUp subscriber signs up and populate key fields.
Create and assign tasks in the Contacts API based on MailUp campaign interactions.
Attach notes to Contacts to capture important engagement details from MailUp campaigns.
Obtain API keys, configure OAuth or API key, and authorize the connection between MailUp and the Contacts API.
Choose endpoints, set triggers, and map fields between systems.
Run tests, monitor logs, and verify data accuracy.
No deep coding is required. This guide uses no-code builders and API connectors to set up the flow. You can configure triggers, actions, and mappings using a visual editor in MailUp and the Contacts API documentation.
Common events include new contact creation, updates, tasks, notes, and campaigns. These events feed into the Contacts API via the defined endpoints and triggers, enabling real-time sync.
Yes. Field mappings let you align essential fields like email, name, and tags. Adjust mapping via the integration setup and test to ensure data integrity.
If a contact is removed in MailUp, you can choose to delete or preserve in Contacts API depending on your workflow. Consider data retention policies and set up reconciliation routines.
Check authentication, endpoints, and mappings; review logs for errors. Use built-in test tools and step-by-step checks to isolate the issue and re-run the sync.
Rate limits depend on your GHL account and the endpoint; refer to the API docs for current limits. Implement retries and backoff in your workflows to avoid throttling.
Use the integration dashboard, logs, and test mode to monitor activity and diagnose issues. Set up alerts for failures and review endpoint responses regularly.
Due to high volume, we will be upgrading our server soon!
