Customer.io Design Studio API

Use these endpoints to manage emails, translations, and components made with Design Studio. You can programmatically manage Design Studio content and migrate templates from an external service. To manage assets like images, use the [Assets API](/integrations/api/app/#tag/assets).These endpoints do not enable you to publish changes to connected workflows like campaigns, nor can you update global styles. They're only for content management at this time. Learn more about the [best practices](/integrations/api/integrate-with-ds/) for sending HTML through these endpoints.If you're an external tool and interested in being listed as one of our integrated partners, please reach out to [product@customer.io](mailto:product@customer.io) to chat with a Product Manager!

Where this information came from

This is an independent, third-party profile of Customer.io Design Studio API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
