SIM Swap - CAMARA - Spain

Integrate real-time SIM card activation checks to enhance security and prevent fraud

Use this API Contact us

The SimSwap API provides the customer the ability to obtain information on any recent SIM pairing change related to the User's mobile account.

HTTPS requests to the REST API are protected with CIBA 3-Legged OAuth.

In short, the API Invoker (e.g. Application Backend or Aggregator) before to request SIM swap check, needs to request a Three-Legged Access Token from Orange Authorization Server. The process follows the OpenID Connect Client-Initiated Backchannel Authentication (CIBA) flow.

Step 1: request the back channel authorization from the application

To authenticate the end-user and obtain her/his consent a GET request must be sent to the bc-authorize endpoint from the user device. This request must provide required parameters.

curl -X POST "https://api.orange.com/es/openapi/oauth/v2/bc-authorize"
-H 'Authorization: Basic encode64(clien_id:client_secret)'
-H 'Content-type:application/x-www-form-urlencoded'
-d 'scope=dpv%3AFraudPreventionAndDetection%23sim-swap&login_hint=tel%3A%2B346xxxxxxxx'

Once the end-user provided her/his consent, the Orange authorization server will send back to the client application an authorization req_id.

200 {"auth_req_id":"69957d77-fea4-4a4c-8cd2-b29f22e61307","interval":2,"expires_in":120}

Step 2: Request the OAuth access token

Once the client application got the authorization code, it has to get the access token protecting the resoures. In order to retrieve it, the client application triggers a POST request to the token endpoint.

curl -X POST "https://api.orange.com/es/openapi/oauth/v2/token"
-H "Authorization: Basic {your application Basic header}" \
-H "Content-Type: application/x-www-form-urlencoded" \
-d "grant_type=urn%3Aopenid%3Aparams%3Agrant-type%3Aciba&auth_req_id=69957d77-fea4-4a4c-8cd2-b29f22e61307"

If the transaction succeeds, in the POST response, the acccess_token is provided.

200 {"access_token":"*****","token_type":"Bearer","expires_in":"119"}

Step 3: Access protected resources using OAuth access token

In order to call our API, the access_token is mandatory.

Base URL

The Base URL is the first part of the full invocation URL, just before the resource paths defined in the API reference.

The Base URL is comprised of the scheme ('https'), the authority (i.e. the Fully Qualified Domain Name) and the API base path.

Whenever you request this API and encounter a 404 (Not Found) HTTP status code, please check first that the Base URL is correct.

The Base URL for this API is: https://api.orange.comcamara/oes/sim-swap/v0

The documentation below assumes that, whenever you make requests on this API, you are prepending the Base URL to the resource paths defined for this API.

Resources

This API has two resources which have their own parameters.

/retrieve-date (POST)

This service returns the timestamp of the most recent SIM card change, capturing the latest alteration between a specific mobile phone number and its corresponding SIM card unique identifier (IMSI).

Request

ParameterDescriptionUsageLocationType
phoneNumberSubscriber number in E.164 format (starting with country code). Optionally prefixed with '+'.MandatorybodyString
