Set up a secure connection from Trello to Blogs API by obtaining an API key or OAuth credentials and granting the required permissions for emails and blogs endpoints.
Authorize Trello to act on your Blogs API data so actions like creating blog posts or updating schedules can be performed from your Trello boards.
Key endpoints used in this connection include GET emails/builder for templates, POST emails/builder/data to save templates, DELETE /emails/builder/:locationId/:templateId to remove templates, GET emails/schedule to view schedules, POST /blogs/posts to create posts, PUT /blogs/posts/:postId to update posts, GET /blogs/posts/url-slug-exists to check slugs, GET /blogs/categories to fetch categories, GET /blogs/authors to fetch authors, and GET blogs/check-slug.readonly to verify slug availability.
Trigger on Trello card creation or when a card moves to a specific list and automatically call POST /blogs/posts to create a new blog post.
Actions include setting the post title from the card title, content from the card description, and optional category and author fields.
POST /blogs/posts
Key fields include title, content, slug, categoryId, and authorId
Trigger when a Trello card reaches Ready to Publish, then update the blog post status via PUT /blogs/posts/:postId.
Actions: update status, publish date, and optionally share across schedules.
PUT /blogs/posts/:postId
Key fields: postId, status, publishDate
Trigger when Trello labels or custom fields indicate metadata changes
Actions: update slug, category, and author via PUT /blogs/posts/:postId
PUT /blogs/posts/:postId
Key fields: postId, slug, categoryId, authorId
Automate workflows without writing code via Trello rules that call Blogs API endpoints
Keep content planning and publishing in one place by linking boards to blog posts
Scale campaigns by reusing templates and cards across teams
This glossary defines terms used in this guide such as GHL API, endpoint, trigger, action, slug, category, and author
The REST API that enables programmatic access to GHL data and actions
A specific URL path for an API operation
An event that starts an automation such as a Trello card move
The operation performed in response to a trigger such as creating a blog post
Turn new Trello cards into draft blog posts in Blogs API by mapping card title to post title and description to content
Schedule publishing via Blogs API using Trello triggers and calendar data
Set slug categories and author fields based on Trello board
Create a Blogs API integration in your GHL dashboard and collect API credentials. Create Trello API key and token.
Set up Trello automation to call Blogs API endpoints when cards move to specific lists or labels
Test with sample cards, verify responses, adjust fields mapping
No coding is required for standard setups. Trello rules can trigger Blogs API calls, and you can map Trello fields to blog post fields. If you already use Trello with automations, you can extend them to manage blogs without writing code. For advanced teams, you can layer in custom scripts if desired, but the base flow is no code.
You will primarily use endpoints that create and update content. Key endpoints include POST /blogs/posts to create posts, PUT /blogs/posts/:postId to update posts, GET /blogs/posts/url-slug-exists to check slugs, and GET /blogs/categories and GET /blogs/authors to enrich posts with metadata.
Yes. Use PUT /blogs/posts/:postId to update an existing post. You can adjust title, content, slug, category, and author fields as part of the update. Ensure you pass the correct postId so changes apply to the intended post.
This guide focuses on the Blogs API but the same approach can be extended to other GHL APIs. You can connect Trello to multiple GHL APIs by creating separate integrations for each API and managing keys or OAuth credentials individually.
Security is maintained through standard API authentication such as API keys or OAuth. Trello credentials are kept separate from Blogs API tokens, and you should follow least privilege principles by granting only needed scopes like emails/builder.readonly or blogs.post.write.
Yes. You can schedule emails by creating a schedule resource in the Blogs API and triggering it from Trello based on card activity. This lets you align email sends with project milestones or publication dates.
Due to high volume, we will be upgrading our server soon!
