Merge customers

You can use this API to complete the following actions:

• Merge 2 customers with different customer_ids
• Update the customer_id of an existing customer in Blueshift

• If no customers are present in our platform with either a combination of email/customer_id or bsft_new_customer_id, a new customer is created with bsft_new_customer_id.
• If both customers exist, the profile data of the old customers will get merged to the new customer (bsft_new_customer_id).
• If there are multiple customer profile matches, for example if you provide an email and there are multiple customers associated with that email, only the most recent customer profile is updated. In such cases, if you have multiple profiles for an email address, we recommend you to use the customer_id instead of email.
• If a customer exists with an email/customer_id, but no customer exists with bsft_new_customer_id, the customer_id of the existing customer is updated to bsft_new_customer_id.

The Merge customers endpoint is throttled at 1500 calls/minute. Reach out to [email protected] if you want to increase the rate limits or if you have any questions.
