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.

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

}

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.

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.

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.

Create a video

Creating a video on Bannerbear is achieved via this endpoint.

This endpoint responds with 202 Accepted after which your video will be queued to generate. Video rendering time depends on length / complexity of the video. It can vary from a few seconds to a few minutes. When completed, the status changes to completed.

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

Parameters

  • video_template stringrequiredThe video template uid that you want to use.
  • input_media_url stringFull url to a video or audio file you want to import as the background of the video. You can also use a static image, and the zoom parameter will be set automatically. This is required depending on the build pack of the template you are using:
    • Build Pack
    • Overlay input_media_url is required
    • Transcribe input_media_url is required
    • Multi Overlay input_media_url is optional
  • modifications listA list of modifications you want to make. See Create an image for more details on the child parameters. Unlike an Image the modifications list is not always required for a Video.
  • zoom stringApply a panning zoom effect to the video or image, can be one of: center, top, right, bottom, left.
  • zoom_factor floatAmount to zoom in by from 1 to 100. If zoom is set and zoom_factor is left blank, this will default to 10.

  • trim_end_time stringTrim the input_media_url clip to a specific end point, using HH:MM:SS notation.
  • trim_to_length_in_seconds integerForce trim the end video to a specific time. There are two ways to trim videos, either you use trim_to_length_in_seconds to trim from the start point by specifying a desired length.
    Or you can use trim_start_time and trim_end_time to specify a part of the video / audio to be used.
  • webhook_url stringA url to POST the full Video object to upon rendering completed.
  • metadata stringAny metadata that you need to store e.g. ID of a record in your DB.
  • frames listApplies only to videos using the Multi Overlay build pack. A list of modifications lists, each one representing a single graphic overlay on the video.
  • frame_durations listApplies only to videos using the Multi Overlay build pack. Custom durations for each frame. When not specified, frames will be spread evenly across the video.
  • create_gif_preview booleanSet to true to create a short animated gif preview in addition to the final mp4.

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.

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.

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.
