API 2.0

Bannerbear API Reference

Bannerbear is a service that auto generates images and videos.

  1. Your designer designs a template in Bannerbear
  2. We turn it into an API
  3. You use this API to generate Images and Videos

See examples in Image Examples and Video Examples.

Base URL

Authentication

Bannerbear uses API keys to allow access to the API. You can get an API key by creating a project in Bannerbear.

Bannerbear expects the API key to be included in all API requests to the server in a header that looks like the following:

Authorization: Bearer API_KEY

You can find the API key in your Project → Settings page.

All API requests on Bannerbear are scoped to a Project.

Endpoint
get/v2/auth
Sample Response
{
  "message": "Authorized",
  "project": "My Project Name"
}

Account

To check your account status at any time you can use this endpoint. It will respond with your quota levels and current usage levels. Usage resets at the start of every month.

Video usage is measured in seconds.

Endpoint
get/v2/account
Sample Response
{
  "created_at": "2019-10-22T09:49:45.265Z",
  "uid": "jJWBKNELpQPvbX5R93Gk",
  "paid_plan_name": "Bannerbear Marketer",
  "image_api_quota": 1000,
  "image_api_usage_this_month": 409,
  "video_api_quota": 3000,
  "video_api_usage_this_month": 1066,
  "current_project": {
    "name": "My Project Name"
  }
}

Errors

The Bannerbear API uses the following status / error codes. The Bannerbear API rate limit is 10 requests per 10 seconds.

202Accepted -- Your request is has been accepted for processing
200OK
400Bad Request -- Your request is invalid.
401Unauthorized -- Your API key is wrong.
402Payment Required -- Your have run out of image and/or video quota.
404Not Found -- The specified request could not be found.
429Too Many Requests -- Slow down!
500Internal Server Error -- We had a problem with our server. Try again later.
503Service Unavailable -- We're temporarily offline for maintenance. Please try again later.

Webhooks

All core resources feature a webhook system so you can be notified when the resource has been generated.

To secure your webhook endpoint, Bannerbear will POST with the following header:

Authorization: Bearer WEBHOOK_KEY

You can find the webhook key in your Project → Settings page.

If a webhook encounters a 4XX or 5XX error, it will be retried up to 5 times with exponential back off.

Async / Sync

The Bannerbear API is primarily asynchronous. When generating a new image, collection etc you POST a request, the API responds immediately with 202 Accepted and you either receive the generated result via webhook or via polling.

This is the preferred pattern as it keeps the request / response cycle predictable.

However, there is a synchronous option if you would simply like to wait for the response in the initial request.

To make a synchronous request use the synchronous base URL. The API required attributes / parameters function the same as normal. Synchronous requests will wait until the media file has finished generating before responding.

There is a timeout of 10 seconds on synchronous requests. Timeouts respond with a 408 status code.

Another option for synchronous image generation is using the signed URLs feature.

Images

Images are the main resource on Bannerbear.

You generate images by sending a POST request with a template uid and a list of template modifications you want to apply. These modifications can be things like: changing the text, changing the images or changing the colors.

Bannerbear will respond with JPG and PNG (and PDF, if requested) formats of the new Image you have requested.

Create an image

Creating an image on Bannerbear is achieved via this endpoint.

This endpoint responds with 202 Accepted after which your image will be queued to generate. Images are usually rendered within a few seconds. When completed, the status changes to completed.

You can poll the GET endpoint for status updates or use a webhook to get the final image posted to you.

This endpoint supports synchronous generation.

Videos

Videos are generated from a Video Template.

Bannerbear can generate 3 types of video:

  1. Overlay a video with a static overlay
  2. Transcribe a video with auto-transcribed subtitles
  3. Multi Overlay a video with a slideshow overlay

These are set at the Video Template level.

You generate videos by sending a POST request with a video template uid, a list of template modifications you want to apply, and a media file.

Bannerbear will respond with an MP4 format of the new Video you have requested.

Collections

Sometimes you want to use the same data payload but push to multiple templates at once.

In Bannerbear, you can do this by grouping templates together in a Template Set. Pushing data to a Template Set results in a response that includes multiple images (depending on how many templates were in your set).

This multi-image object is known as a Collection.

Video Templates

Video Templates are a subset of Templates.

Templates for Images hold design / layout information - as would be required to render Images.

Video Templates simply hold some extra instructions, telling Bannerbear what kind of video to render.

These are called Build Packs and there are 3 types:

  1. Overlay a video with a static overlay
  2. Transcribe a video with auto-transcribed subtitles
  3. Multi Overlay a video with a slideshow overlay

Movies

A Movie is a series of Video clips joined together in sequence, using optional transitions, into a single MP4 file. Bannerbear handles the cropping and encoding of files automatically.

An example use case for a Movie is when your business has videos with a consistent intro and outro, and you want to place dynamically-generated Video content from the Bannerbear /videos endpoint between them.

Another use case for a Movie is when you want to join static images together in an MP4 slideshow with transitions.

Fonts

Fonts are set at the template level in Bannerbear. When you design a template and create a text box, you choose a font for that text box. So it is not necessary to set fonts when creating images via the API, as the defaults will be used.

However, if you wish you can change fonts in your images on-the-fly when creating an image by adding a font_family parameter and the name of a valid font.

If you use an invalid font name when creating an image, the template default font will be used.

This endpoint simply returns a list of valid fonts.

Effects

Bannerbear has a number of built-in effects that you can apply to image containers at the template level.

However, you can also set these on-the-fly when you make Image API requests using the effect property.

This is useful if you need to make multiple variations from a template, but use different effects in each one.

This endpoint simply returns a list of valid effects.

  "Smart Crop",
  "Grayscale",
  "Sepia",
  "Gaussian Blur",
  "Grayscale + Gaussian Blur",
  "Flip Horizontal",

Diagnoses

Sometimes an image you generate on Bannerbear may not turn out as expected.

The most common problem is with imported images, which is the current focus for this diagnostic tool.

An imported image may be missing at the origin, or blocking Bannerbear access etc. This is usually due to permissions, file formats etc, but it can be tedious to track down the root cause.

This endpoint helps you isolate the problem, given an Image ID.

When you create a Diagnosis, Bannerbear will run through a series of checks on the data in the Image you have requested the diagnosis for. You will then receive a report with issues and suggested fixes.

The subtle difference between the singular Diagnosis and plural Diagnoses is easy to miss. Ensure you use the right spelling when using this endpoint.
