Pass Values in a REST API Query

This guide gives you an overview of how you can pass values in a REST API Query using raw JSON and key-value pairs, enabling real-time data fetching, updates, and user-driven workflows.

Raw JSON

In the following JSON code, the ${} syntax is used for JavaScript string interpolation within template literals (also called template strings). This allows dynamic values from JavaScript variables or expressions to be injected directly into the string.

{
  {
    `{
     "contents": [{
       "parts": [{
         "text": "Generate the following content for this image in markdown format:
            content type: ${components.typeOfContentInput.value},
            additional info: ${components.additionalInfoInput.value}"
        },
        {
            "inline_data": {
              "mime_type":"image/jpeg",
              "data": "${components.imageUploader.file[0].base64Data}"
            }
          },],
      },],
    }`;
  }
}

Supported Ways to Pass Values

ToolJet supports passing values into REST API queries in multiple ways:

Method	Description	Example
Headers	Authentication or metadata	Authorization: Bearer {{globals.token}}
Params	filters, search, and pagination	?tone={{components.tone.value}}
Body	sending structured or complex data	{ "prompt": {{components.prompt.value}} }
Cookies	send session-related data	{{globals.sessionId}}

Entering Key Value Pairs

In this example, simple key-value pairs are entered in the provided input fields. Here, the values can simply be passed using double curly braces as is typically done in ToolJet. Take note of the status key. A string is combined with another value that is referred using double curly braces.
