The partner's group must already have a discount assigned to it, and the discount code must be associated with a link that is not already linked with another discount code. The partner's group must already have a discount assigned, and each referral link can only have one discount code. If you omit `code`, Dub generates one from the partner's name. ## OpenAPI ````yaml post /discount-codes openapi: 3.0.3 info: title: Dub API description: >- Dub is the modern link attribution platform for short links, conversion tracking, and affiliate programs. version: 0.0.1 contact: name: Dub Support email: support@dub.co url: https://dub.co/support license: name: AGPL-3.0 license url: https://github.com/dubinc/dub/blob/main/LICENSE.md servers: - url: https://api.dub.co description: Production API security: [] paths: /discount-codes: post: tags: - Discount Codes summary: Create a discount code description: >- Create a discount code for a partner.
