Obtain API keys for both Blogs API and MailerSend from their developer portals
Map endpoints to data models and set the proper permissions and scopes such as emails/builder.readonly
Test thoroughly, verify data flow, monitor logs and deploy to production
No coding is required for basic connections. You can connect the Blogs API and MailerSend using standard API keys and endpoint mappings. If you want more control you can extend the integration with custom logic, but the no code path covers typical use cases. Always test in a sandbox before going live.
Start with retrieving templates and categories to understand data structures. Use GET emails/builder to pull templates and GET /blogs/categories to learn categories. Then configure create and update endpoints and test the flow end to end.
Use a staging environment to run test posts and templates. Validate that templates from MailerSend appear in the Blogs API and that post publication events trigger the expected emails. Use logging and audit trails to verify data matches across systems.
Protect your API keys and use least privilege scopes. Rotate keys regularly and use IP allowlisting if available. Prefer tokens and signed requests where supported and monitor for unusual activity.
Yes. Scheduling is supported via the emails schedule endpoints and blog post scheduling. You can queue email sends and align blog publication with newsletters to create consistent cadence.
A slug is a URL friendly version of a post title. It helps produce readable, SEO friendly links. Ensure slug uniqueness and use the slug existence endpoint when creating new posts.
API keys are generated in each service developer portal. Retrieve the Blogs API key from its portal and the MailerSend API key from its account. Store keys securely and do not expose them in client code.
