Generate Branded Graphics Programmatically
Integrate RepeatPosts into your workflow with a REST API. Create API keys, send template data via HTTP, receive rendered images in response, and listen for completion via webhooks.

RESTful Endpoints
Simple JSON payloads let you specify a template, data fields, output format, and size. Receive a rendered image URL or binary response within seconds.
Webhook Notifications
Register webhook URLs to receive POST callbacks when images finish rendering. Ideal for async pipelines and large batch operations.
API Key Management
Create multiple API keys with independent rate limits, scoped permissions, and usage dashboards. Rotate keys without downtime.
How It Works
Create an API Key
Generate an API key from your dashboard. Set a rate limit and optional webhook URL for async image delivery.
Send a Render Request
POST a JSON payload with the template ID, field values, and desired output format. The API validates your data and queues the render.
Receive Your Image
Get the rendered image back as a direct download URL or a webhook callback. Integrate the URL into emails, ads, or social schedulers.
