You can send an image to an API from your Dropsource app. Your image can come from inside the app, or elsewhere on the user device, such as the camera or gallery. In order to receive the image, your API should be set up to receive base 64 encoded image strings.
- Add an Image Element to a page in your app. You can set the Image Asset in Properties by uploading an image manually into your project, or if you want to let the user upload their own image, use either the Take a Photo / Pick an Image Action on Android, or the Select Image from Photos Action on iOS (it allows you to select from the camera or photo library).
- To send the image as a Base 64 encoded string, your app will need to encode the image and store it in a variable to send with the API request. In Page Variables on the right of the editor, create a new variable, with a name of your choice and Swift/Java String type.
- Add the API request that receives the image. In the Parameters, find the field that expects the image string. If you’re sending it as a Base 64 encoded string, bind the field to the Page Variable you created.
When your request runs, it will send the image as a parameter. For a complete example of sending images to an API, check out the Photo Saver example app. You can also display images from API responses, including arrays.
