API code samples

This page contains code samples for the Google Spectrum Access System (SAS) Portal API.

Before you begin

For the following examples, ensure that you complete the following prerequisites:

Obtain a token with your service account TOKEN=$(gcloud auth print-access-token) .
Set ${CLIENT_PROJECT} to the project ID of the Google Cloud project.

List current customers

Return all of the customers that the caller has access to:

curl -X GET -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
 -H "Content-Type: application/json" \
 -H "Authorization: Bearer ${TOKEN} 
" \"https://sasportal.googleapis.com/v1alpha1/customers"

Save the customer name that is returned as a variable:
```
CUSTOMER_NAME=customers/...
```

Create a new device configuration

Set the ${FCCID} and ${SN} of the device that you want to create:
```
FCCID=f1
SN=sn1
```

Create the device configuration:

curl -X POST -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
 -H "Content-Type: application/json" \
 -H "Authorization: Bearer ${TOKEN} 
" \ "https://sasportal.googleapis.com/v1alpha1/ ${CUSTOMER_NAME} 
/devices" \
 -d "{ \"fcc_id\": \" $FCCID 
\", \"serial_number\": \" $SN 
\", \"preloaded_config\": { \"call_sign\": \"cs1\", \"category\": \"DEVICE_CATEGORY_A\"}}"

The command returns a newly created device configuration.

Save the device name as a variable:
```
DEVICE_NAME=customers/.../devices/...
```

List current devices

curl -X GET -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
 -H "Content-Type: application/json" \
 -H "Authorization: Bearer $TOKEN 
" \ "https://sasportal.googleapis.com/v1alpha1/ ${CUSTOMER_NAME} 
/devices"

Retrieve devices by name

curl -X GET -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
 -H "Content-Type: application/json" \
 -H "Authorization: Bearer $TOKEN 
" \
 "https://sasportal.googleapis.com/v1alpha1/ ${DEVICE_NAME} 
"

Update an existing device

curl -X PATCH -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
 -H "Content-Type: application/json" \
 -H "Authorization: Bearer $TOKEN 
" \
 "https://sasportal.googleapis.com/v1alpha1/ ${DEVICE_NAME} 
" \

Validate your Certified Professional Installer (CPI) identity and certification

Generate the secret string:

curl -X POST -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
 -H "Content-Type: application/json" \
 -H "Authorization: Bearer $TOKEN 
" \ "https://sasportal.googleapis.com/v1alpha1/installer:generateSecret" \
 -d "{}"

The output is similar to the following:

{
  "secret": "<generated secret>"
 }

Use the JSON Web Token format to encode the secret string into a JWT.
Set the following:
1. ${SECRET} to the secret string
2. ${ENCODED_SECRET} to the JWT string
3. ${CPI_ID} to the ID of the CPI

Validate the identity and certification of the CPI:

curl -X POST -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $TOKEN 
" \ "https://sasportal.googleapis.com/v1alpha1/installer:validate" \
  -d "{ \"installer_id\": \" ${CPI_ID}\ 
", \"secret\": \" ${SECRET}\ 
", \"encoded_secret\": \" ${ENCODED_SECRET}\ 
" }"

Now the CPI can install a Citizens Broadband Radio Service Device (CBSD) that has all the required parameters.

Multistep CBSD registration

You can perform multistep CBSD registration with device parameters previously signed by a CPI or with a CPI account.

Device parameters previously signed by a CPI

This sample shows how to create an inactive device configuration with CBSD installation parameters previously encoded by a CPI. As a result, the non-CPI users can also create the configuration.

Use the CPI's private key to encode the CBSD parameters. We recommend that you use the JSON Web Token format .
Set ${ENCODED_DEVICE} to the JWT string and ${CPI_ID} to the ID of the CPI.

Create the inactive device configuration:

curl -X POST -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer ${TOKEN} 
" \ "https://sasportal.googleapis.com/v1alpha1/ ${CUSTOMER_NAME} 
/devices:createSigned" \
  -d "{ \"installer_id\": \" ${CPI_ID} 
\", \"encoded_device\": \" ${ENCODED_DEVICE} 
\", \"parent\": \" ${CUSTOMER_NAME} 
\" }"

The CBSD must then send a registration request to SAS to complete its registration.

CPI account

The CPI's identity must be validated before you validate a device configuration. When that is done, use the following command to create an inactive device configuration:

curl -X POST -H "X-Goog-User-Project: ${CLIENT_PROJECT} 
" \
    -H "Content-Type: application/json" \
    -H "Authorization: Bearer $TOKEN" 
\ "https://sasportal.googleapis.com/v1alpha1/ ${DEVICE_NAME} 
:signDevice" \
    -d " ${DEVICE} 
"

Replace ${DEVICE} with the JSON representation of the CBSD registration parameters. For more information about the format, see REST Resource: customers.devices .

The CBSD must then send a registration request to SAS to complete its registration.
