Safely Posting JSON Data with cURL

Posting JSON Data as Payload

When posting JSON data as payload, we can use the following commands in our terminal:

terraform_api='https://app.terraform.io/api/v2'
url=${terraform_api}/runs
helper_tf_apply_destroy='your-terraform-api-token'

response=`curl -s -X POST -H "Authorization: Bearer ${helper_tf_apply_destroy}" -H "Content-Type: application/vnd.api+json" ${url} --data '{"comment":"Confirm Apply"}'`

In this example, we're posting a JSON payload with the comment "Confirm Apply". You can modify the --data option to include your own JSON data.

Posting JSON File as Payload

Sometimes, we may need to post a larger JSON file as payload. In that case, we can use the following commands:

terraform_api='https://app.terraform.io/api/v2'
url=${terraform_api}/runs
helper_tf_apply_destroy='your-terraform-api-token'
dir=$(pwd)

response=`curl -s -X POST -H "Authorization: Bearer ${helper_tf_apply_destroy}" -H "Content-Type: application/vnd.api+json" ${url} --data @${dir}/payload.json`

In this example, we're posting the contents of a file named payload.json located in the current working directory. Make sure to modify the --data option to include the correct path and filename.

Customizing Header

When posting JSON data, we may need to customize our header authentication and content type. For example:

-H "Content-Type: application/json"

This sets the content type of the request to application/json, which is suitable for most JSON-based APIs.

In conclusion, posting JSON data with cURL is a straightforward process that can be achieved using the commands outlined above. By modifying your header and payload as needed, you'll be able to successfully interact with your API endpoints.
