Number of promo codes in one requestThe API can update a maximum of 1000 promo codes per request. If an API call includes more than 1000 promo codes, a 400 error will be returned. To update more than 1000 promo codes, we recommend dividing them into multiple API calls.
Things to know before you start
- Replaces all codes: This endpoint removes ALL existing codes and replaces them with the new set. Use "Add promo codes" to append codes instead.
- 1000 code limit: Maximum 1000 codes per request. For larger batches, split into multiple API calls.
- Promotion UUID required: Get it from the promotion URL in Blueshift app or from the promotion id field.
Finding the promotion UUIDYou can find the promotion UUID in two places when viewing a promotion in the Blueshift app:
- In the URL:
https://app.getblueshift.com/dashboard#/app/promotions/<PROMOTION_UUID>/edit- In the Promotion id field on the promotion edit page
- Response counters: Returns
available_codes(unused) andtotal_codes(all codes in promotion after replacement). - Irreversible action: Previous codes are permanently removed. Consider backing up existing codes before overwriting.
