Tutorial: How to Create Images by API

It is common for marketing visuals to follow a similar design. Here's where automation templates come in. A template is a reusable design where certain elements are automatically replaced to generate thousands of unique derivatives. These elements can be product images, names, prices, titles, etc. Here is an overview of how this works to auto-generate visuals for social media, e-commerce, email personalization, and more.

Create an image template

The first step in automating visuals is creating a reusable template. This design consists of dynamic elements, such as text, colors, and images, all of which can be replaced using an image API.

There are a variety of ready-made video templates available, but you can create your own image designs using the online editor. This allows you to automate images and animated GIFs for virtually any marketing purpose.

curl -s -X POST \
  -H 'Authorization: Bearer Your-API-Key' \
  -H 'Content-Type: application/json' \
  --data-binary @- << EOF

Generate images using the API

Once you have created an image template, you can use the API to automate the process by providing different content to be placed within the template. It's just a matter of specifying the template ID and values you want to insert into the template.

The API can be invoked by any programming language or no-code tool such as Zapier. This lets you generate any number of images completely automatically from your own software application, or no-code workflows.

Fully automate the image creation process

Whatever type of marketing visuals you need to create, you can set up an automated workflow that works for you. You could, for example, generate social media posts from a Google Sheets spreadsheet or Airtable document. Or if you have an online store, you could create visuals for your products. And you can also add dynamic images or GIFs to your email marketing campaigns to send your subscribers personalized visuals.

In case you don't need a fully automated workflow, you can also create visuals using a simple spreadsheet or form. These methods do not require API integration, so be sure to check out those tutorials as well.
