Troubleshooting

How do I fix a server error?

Server errors are likely due to one of the following issues:

  1. The Facebook account that was used to integrate with Sendlane has not accepted the terms of service for Facebook Custom Audiences. Log in to the Facebook account that was used to connect with Sendlane and accept the terms of service, then log out of Sendlane and back in.

  2. The Facebook account that was used to integrate with Sendlane was given read-only access to the Facebook business account. Provide full access to the Facebook account used to manage the Facebook Custom Audience.

  3. You have reached or exceeded Facebook's limit of 500 or more audiences. You can make room in your account by creating lookalike audiences for other audiences, but be aware that lookalike audiences will not sync with Sendlane.
