Common payload errors
When troubleshooting Kajabi Webhooks, you may encounter the following payload errors:- email: can’t be blank
- name: can’t be blank
- email: is invalid

Additional information when troubleshooting webhooks
- Webhooks always require the name, email, and external_user_id. All values should be lowercase.
- The external_user_id will be prioritized over email.
- The easiest way of making the email and external_user_id match is to use the email address as the external_user_id. If you need assistance updating your existing users’ external_user_ids to be the email address, reach out to Support.
- Make sure the required Key-Value Pair/payload is on the top-level. If it’s nested underneath it will not work and will give you the “Email can’t be blank and Name can’t be blank” error as shown below.
