Sometimes, when running an ActiveCampaign backup, users may encounter the following error: The remote server returned an error: (403) Forbidden
This happens when the ActiveCampaign API receives too many requests in a short period, especially if the Accounts, Contacts, or Deals tables contain numerous records.
Skyvia supports custom fields for Accounts, Contacts, and Deals in a hybrid implementation. When the Use Custom Fields option is enabled, Skyvia sends an additional API request for each record to fetch custom field values. This can overload the ActiveCampaign API, resulting in 403 Forbidden or Timeout errors.
If you do not need custom fields, it is recommended to disable them:
This reduces the number of API requests and prevents 403 errors.
If you only need standard object data, exclude custom fields from the backup selection to reduce API load and prevent errors.
