Documentation for Gravity Forms Send to API

Merge tag manipulations

You can manipulate merge tag values before you send them to your API.

Need to uppercase a something? Simply: {gfsta_manipulation value="{FirstName:3}" uppercase}

Say you need to send an image of a signature as base64 encoded string. The Gravity Forms Signature add-on will allow you to add the signature field, but only provides a URL of the image afterwards.

Now, in the body, you can add a merge tag that base64 encodes this image like so:

{gfsta_manipulation value="{Signature:3}" base64_encode="url"}

These manipulations will also work on merge tags created from the API response. If you want, for example, to only get the last name of a full name value:

{gfsta_full_name split_get="1| "}

Or get the longitude of a value that holds the lat/long values comma seperated:

{gfsta_coordinates split_get="last|,"}

The full list of manipulations:

Manipulation Description Example
uppercase Uppercase a value {gfsta_first_name uppercase}
lowercase Lowercase a value {gfsta_first_name lowercase}
date_format Format a date value {gfsta_created_at date_format="Y-m-d"}
split_get Split and then get a value {gfsta_coordinates split_get="0|,"} where 0 is the index and , the seperator. As index, you can also pass first or last
base64_encode Base64 encode a value {gfsta_image base64_encode} or for a URL input {gfsta_image base64_encode="url"}
manipulation You can use this to manipulate other merge tag values. You need to set the value first. {gfsta_manipulate value="{FirstName:3}" uppercase}
