Frequently asked questions

Do I need to code to connect GHL and EmailOctopus?

Answer: You can connect without coding using a no-code platform or the native integration. Step-by-step guides cover authentication and field mapping to get you started. If you need more control, you can extend the setup with custom automation and advanced mappings.

Answer: For a basic sync, start with listing and reading contacts (GET /contacts/:contactId, GET /contacts/). Use POST /contacts/ to create and PUT /contacts/:contactId to update. This provides a foundation for syncing essential contact data, and you can expand to tasks and notes as needed. Pagination and filtering help manage larger datasets.

Answer: Authenticate via API key or OAuth token for the GHL Contacts API. Securely store credentials and apply the required scopes. For EmailOctopus, use the app’s API token or OAuth flow if available. Always follow best practices for credential management and rotate keys periodically.

Answer: Yes. You can trigger actions in EmailOctopus from GHL events by wiring event-driven triggers (such as contact updates or new notes) to corresponding actions in EmailOctopus (like creating or updating contacts or notes). Webhooks or polling can be used to drive these automations.

Answer: There can be rate limits depending on your plan and API usage. Plan for pagination and batching to stay within limits. If you encounter limits, stagger requests or apply backoff strategies, and consider upgrading for higher throughput. No single page should exceed typical API rate boundaries if you design your workflow carefully.

Answer: Handle conflicts by defining the source of truth (e.g., GHL as the primary source) and using last-modified timestamps to resolve disparities. Implement idempotent operations where possible and log changes for traceability. Consider implementing a reconciliation step during each sync cycle.

Answer: The API endpoint list and examples are available in the documentation. It includes endpoints for contacts, tasks, notes, and appointments, and demonstrates typical request/response patterns. Use the endpoint catalog as a reference when designing mappings and automation rules.
