Send your first request

Before you start

Before you make your first API request, you need:

Access details for authentication — see Authentication.
Installed curl utility — this example uses the curl command-line utility to invoke the API.

Invoke the listContracts operation

To invoke the listContracts operation:

On a Linux or UNIX platform, set the following environment variables, using the values from your access details:

 export TOKEN_URL="XXXXXXXXXX"
 export BASE64_KEY="XXXXXXXXXX"
 export API_BASE_URL="https://platform.iceye.com"

Send a request to the Token endpoint to obtain an access token:

 curl --request POST \
 --url "${TOKEN_URL}" \
 --header "Accept: application/json, application/problem+json" \
 --header "Authorization: Basic ${BASE64_KEY}"" \
 --header "Cache-Control: no-cache" \
 --header "Content-Type: application/x-www-form-urlencoded" \
 --data "grant_type=client_credentials"

If the request is successful, you should receive a response like the following:

 {
   "token_type":"Bearer",
   "expires_in":3600,
   "access_token":"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX",
   "scope": "catalog.read deliveries.read orders.read activities.read contracts.read internal_options.read customers.read internal_options.write"
 }

Extract the access_token property from the authentication response and use it to define the API_ACCESS_TOKEN environment variable:
```
 export API_ACCESS_TOKEN="XXXXXXXXXX"
```

Invoke the listContracts operation, as follows:

 curl --location "${API_BASE_URL}/api/company/v1/contracts" \
 --header "Accept: application/json, application/problem+json" \
 --header "Authorization: Bearer ${API_ACCESS_TOKEN}"

Contract IDs

If successful, the response to the listContracts invocation contains a list of one or more contracts associated with the current user’s company:

{
  "data": [
    {
      "id": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX",
      "name": "string",
      ...
    }
  ],
  "cursor": "string"
}

Each of the listed contracts has an id property, which defines the contract ID for that contract.

Contracts play a crucial role in the ICEYE Constellation API Suite (ICAS), because they define constraints that affect the parameter values you are allowed to set in API requests.

Make a note of the contract ID and store it in a safe place. For many of the ICEYE API operations, the contract ID is a required parameter.
