There may be times when you no longer need an integration or when the credentials have changed -- for example, after a password reset in Billbee or the creation of a new access token in Shopify. In both cases, you can easily make adjustments in AutoLetter.
If your API credentials have changed (new password, new token), you do not need to delete and recreate the integration. Instead, you can update the credentials directly:
Navigate to Integrations and click on the integration whose credentials you want to update.
In the integration details, you will find the credential fields. Click Edit or the corresponding edit icon.
Enter the new credentials:
AutoLetter automatically verifies the new credentials. On successful connection, the changes are saved and synchronization continues with the new data.
If synchronization suddenly fails, it is often due to expired or changed credentials. In this case, first check whether your API credentials are still up to date.
If you permanently no longer need an integration, you can delete it completely:
Navigate to Integrations and select the integration you want to remove.
Click the Remove or Delete button.
A confirmation dialog appears, requiring you to explicitly confirm the deletion. This step prevents accidental deletion.
When you delete an integration, the connection to the data source is severed. However, previously imported orders and customer data remain in AutoLetter and can continue to be used in campaigns. No order data is deleted -- only the connection to the external platform is removed.
This means specifically:
If you are unsure whether you still need an integration, you can alternatively disable automatic synchronization instead of deleting the integration. This way, the connection remains intact and can be reactivated at any time.
