Description

Acording the docs and code the packer http datasoruce only supports GET while the Terraform datasouce supports multiple HTTP methods. Since it is mostly just copied it should be feature equivalent. During the build users may want to get data based on inputs. Most APIs require the data to be in the body so a POST/PUT is needed or recommended.

Use Case(s)

• Query data from a remote API based on inputs
• Send packer build artifacts (checksums, sboms...) to an artifact store
• Configure packer created services via a POST request
• Check if the packer created resources was successfully created or is healthy
• Send information to a communication channel via a webhook

Potential configuration

data "http" "example_post" {
  url    = "https://checkpoint-api.hashicorp.com/v1/check/terraform"
  method = "POST"

  # Optional request body
  request_body = "request body"
}
