To begin, generate an API key from your GHL account with the scope emails/builder.readonly so LettrLabs can read and compose emails and access post data.
Grant LettrLabs permission to access the Blogs API on your GHL account by completing the OAuth flow or providing the API credentials in the integration settings.
Used endpoints include: GET emails/builder, POST emails/builder, POST /emails/builder/data, DELETE /emails/builder/:locationId/:templateId, GET emails/schedule, GET /blogs/posts/url-slug-exists, blogs/post.write, POST /blogs/posts, PUT /blogs/posts/:postId, GET /blogs/categories, GET /blogs/authors.
Trigger: a new blog post is published in the Blogs API (blogs/posts) and a corresponding email is prepared in the LettrLabs builder
Actions: map post data to an email draft in emails/builder, then schedule or send via emails/schedule
Methods and paths: GET /blogs/posts, POST /blogs/posts, GET /blogs/posts/url-slug-exists, GET /blogs/categories, GET /blogs/authors
Key fields: postId, title, slug, date, excerpt, author
Trigger: post updates in the Blogs API (blogs/post-update.write)
Actions: update emails/builder data and templates, then re-send or re-schedule affected campaigns
Methods and paths: PUT /blogs/posts/:postId, POST /blogs/posts
Key fields: postId, slug, updatedAt, title
Trigger: new or updated categories/authors in the Blogs API
Actions: pull blogs/categories and blogs/authors and update LettrLabs audience segments and templates
Paths: GET /blogs/categories, GET /blogs/authors
Key fields: categoryId, name; authorId, name
No coding required: use pre-built endpoints to automate blog email workflows inside LettrLabs.
Faster campaigns: configure triggers and actions with a visual editor and no custom code.
Scalable content: manage multiple blogs, categories, and authors with simple mapping rules.
This glossary explains core elements and processes you’ll use when integrating the GHL Blogs API with LettrLabs, including endpoints, authentication, and data mapping.
A specific URL you call to access a service’s data or functionality.
The process of verifying identity to grant access to an API.
Permissions attached to an API key or OAuth token that determine what actions are allowed.
A real-time notification mechanism that sends data from one app to another when events occur.
When a new post goes live, LettrLabs can generate a ready-to-send email draft using the post title, excerpt, and image.
Group posts by category and automatically assemble a digest email to subscribers.
Create targeted campaigns that feature posts from specific authors to grow engagement.
In GHL, generate an API key with the required scope for reading and writing emails, then copy the key into LettrLabs.
Follow the OAuth flow or paste the API key to authorize LettrLabs to access Blogs API endpoints.
Run a test by pulling a post or creating a sample email to ensure data maps correctly.
Permissions are defined by the scope you grant when generating the API key. For read/write email templates and post data, use the scope emails/builder.readonly and related endpoints to ensure LettrLabs can read posts and compose emails. In LettrLabs you can map fields from blog posts to your email templates, control when emails are sent, and test the flow without touching code.
LettrLabs uses a curated set of Blogs API endpoints by default to read posts, fetch categories and authors, and publish emails. You can customize which endpoints are active. You can review and adjust end-user flows in LettrLabs’ integration settings to align with your content strategy.
Yes. You can map post fields (title, slug, date, excerpt) to template placeholders in LettrLabs so each email reflects the post. Updates to the post data can trigger rebuilt emails or updated templates automatically.
Security best practices include keeping API keys secret, using rotating credentials, and restricting scopes. Use LettrLabs’ secure storage and monitor API usage; revoke access if needed.
A developer account or access to the GHL developer portal is recommended for configuring OAuth credentials. In production, use securely stored keys and verify permissions before enabling webhooks.
If the connection is interrupted, re-authenticate and re-run the setup to re-map fields. Test calls to endpoints such as GET /blogs/posts or GET /blogs/authors to confirm the connection is restored.
Yes. LettrLabs lets you customize mappings and templates so you can control which post data appears in each email. You can adjust triggers and actions to fit your content cadence without coding.
Due to high volume, we will be upgrading our server soon!
