Use a secure API key scoped to the required resources. If your workflow needs broader access, request read/write permissions and rotate keys regularly. For OAuth scenarios, follow the standard OAuth 2.0 flow to obtain access and refresh tokens and store them securely.
Authenticate MailerLite Classic with an API key that has the necessary scopes. Keep credentials secret, rotate keys periodically, and use least-privilege access. If using OAuth, ensure redirect URIs are registered and tokens are renewed automatically.
Key endpoints include: GET emails/builder, GET emails/builder.write, POST emails/builder, POST /emails/builder/data, DELETE /emails/builder/:locationId/:templateId, GET emails/schedule, GET /blogs/posts/url-slug-exists, POST /blogs/posts, PUT /blogs/posts/:postId, BLOGS endpoints such as blogs/post.write, blogs/post-update.write, blogs/check-slug.readonly, GET /blogs/posts/url-slug-exists, blogs/category.readonly, GET /blogs/categories, blogs/author.readonly, GET /blogs/authors. Use the endpoints that align with your workflow and data needs.
Trigger: when a new or updated blog post is detected in the GHL Blogs API.
Actions: fetch post data (GET /blogs/posts or PUT /blogs/posts/:postId), create or update an email draft via GET/POST emails/builder or POST /emails/builder/data, optionally schedule via GET emails/schedule.
PUT /blogs/posts/:postId
postId, title, slug
Trigger: schedule-based delivery aligned with your editorial calendar.
Actions: read schedule (GET emails/schedule), assemble email content, queue or send via emails/builder endpoints.
GET emails/schedule
scheduleId, time
Trigger: a subscriber action or preference change can trigger updated content in an email.
Actions: update content via POST /emails/builder/data and refresh the related email draft using PUT/DELETE as needed.
POST /emails/builder/data
recipientId, contentId, templateId
Automates content-to-email workflows without writing code.
Keeps content and campaigns in sync across platforms from a single interface.
Speeds up time to value with pre-built endpoints and templates.
This glossary defines the terms used in this guide and explains how they relate to the GHL Blogs API and MailerLite Classic integration.
A specific URL and HTTP method used to access or modify a resource in an API.
The process of proving identity and gaining access to API resources, typically via API keys or OAuth tokens.
A secret token used to authorize API requests, usually scoped and rotated for security.
A URL endpoint that receives real-time updates from an API when events occur.
Automatically fetch new posts and create draft emails in MailerLite Classic for a weekly roundup.
Push updates to subscribers when posts are edited and republished; personalize content by segment.
Use templates to turn posts into ready-to-send emails via the builder data endpoint.
Generate and store API keys for both APIs and grant the necessary scopes. Verify credentials in a test environment.
Select endpoints (e.g., GET emails/builder, POST /blogs/posts) and align fields like postId, title, and content with your email templates.
Run dry runs, validate payloads, check error handling, then enable automatic syncing in production.
You can connect MailerLite Classic with the GHL Blogs API without custom code. The setup uses API keys and endpoint calls to pull posts and create email drafts, all inside your automation platform. Start by generating a read/write key for the Blogs API and a key for MailerLite Classic, test payloads in a safe environment, and ensure the required scopes are granted before going live.
Begin with endpoints that fetch content and create drafts, such as GET emails/builder and POST /blogs/posts. Next, map fields (postId, title, content) to your email templates and run end-to-end tests to verify posts render correctly in newsletters.
Authentication leverages API keys or OAuth tokens. Keep keys secret and rotate them regularly; align scopes to your needs (readonly vs read/write). If using OAuth, exchange authorization codes for tokens and refresh before expiry; store tokens securely.
Yes. You can schedule newsletters based on blog content using the schedule endpoint and builder data to assemble emails. Validate time zones, cadence, and recipient lists in your test environment before enabling automation.
Follow best practices: clearly map fields, validate IDs, and handle errors gracefully. Use a small subset of templates during pilot and document your mappings to reduce complexity during rollout.
Use a sandbox or test environment to run end-to-end workflows, then monitor payloads and delivery status. Set up alerts for failures and use logs to troubleshoot payload mismatches.
You can find more resources in the official API docs for GHL and MailerLite Classic, our integration guides, and example workflows. If you need help, reach out to support or use community forums for patterns and tips.
Due to high volume, we will be upgrading our server soon!
