Converting a Rich Text Area Field's Image for API Upload

Post by API Doc'er  (2011-06-17)

Uploading Images Using the API

If records include rich text area fields containing images, you must convert the image to Base64 and supply that as the value in the relevant field. You can use a text editor to do this.

Solution

  1. Encode the desired image into Base64.
  2. Copy the entire Base64 image string to the clipboard.
  3. Copy the following text and paste it into a text editor: 
    <img alt="<image_Name>" src="data:image/<image_File_Extension>;base64, <base64_Image_String>"></img>
    • Replace <image_Name> with the file name of the image. Don’t include the file extension. For example: Headshot1
    • Replace <image_File_Extension> with the extension of the image file. Don’t include the dot. For example: jpg
    • Replace <base64_Image_String> with the string that you copied in Step 2.
  4. Copy the entire source text data and use it as the value in the relevant field of the API.
  5. Upload the data.

I just wanted to point out a possible error based on the code above. There is a space between ";base64," and "<base64_Image_String>". I believe it is just a typo but having that space there caused an error, removing it did the job. Just something to look out for.

Dear Sir,

We are building an iOS app that needs to download and display images from a custom Rich Text field in the User object.

We are following your approach, the problem we face is within "step 1": Encode the desired image into Base64.

This is when we "grab" the image itself from its URL contained in the rich-text area. When we perform the request for the image itself we are blocked by an authorization/access rights problem even though the session is already authorized.

Thanks for any help you can give!
