Test account linking

You can simulate creating an Instacart user and then linking a user account with an Instacart account.

1. Call the Authorization endpoint. This call generates the access token.

curl --location --request POST 'https://<instacart_development_domain>/v2/oauth/token' \
--header 'Content-Type: application/json' \
--header 'X-Retailer-Id: the-garden' \
--data-raw '{
  "grant_type": "client_credentials",
  "client_id": "<client_id>",
  "client_secret": "<client_secret>"
}'

The response contains the linking token in the access_token field.

{
  "access_token": "l0ebkrG2JAXEuNI9UBpWXO-yC7asltvuyw4RjELk3Hc",
  "token_type": "Bearer",
  "expires_in": 86400,
  "scope": "connect:fulfillment",
  "created_at": 1615821019
}

2. Create an Instacart user. This generates the user id.

curl --location --request POST \
    --url 'https://<instacart_development_domain>/v2/fulfillment_sandbox/instacart_users' \
    --header 'Accept: application/json' \
    --header 'Authorization: Bearer <token>' \
    --header 'Content-Type: application/json' \
    --data '{
    "email": "kamalsingh1234@gmail.com",
    "password": <string>,
    "phone": "8005550101",
    "express_member": true
}'

The response contains the user id. You use the user id to generate an authorization code.

{
  "id": 940626754
}

3. Request authorization to link accounts. Use the user id to generate an authorization code.

curl --location --request POST \
    --url 'https://<instacart_development_domain>/v2/fulfillment_sandbox/instacart_users/940626754/authorize' \
    --header 'Accept: application/json' \
    --header 'Authorization: Bearer <token>' \
    --header 'Content-Type: application/json' \
    --data '{
   "response_type": "code",
   "client_id": "e1c700be60cc57c0154ff5aeb3bb57fd079d01dd159fcd85133a3c7c62446ad4",
   "scope": "openid account_linking",
   "state": "b1a2c3e4f6",
   "redirect_uri": "https://example.org",
   "hint": "https://example.org"
}'

The response contains the authorization code.

{
  "code": "R5n9Jx1LPgXAwAtzxsepptyHHT9K1Cx4qckfc-qZh6c"
}

4. Link the accounts.

curl --location --request POST 'https://<instacart_development_domain>/v2/fulfillment/users/38b15dd0-150d-40cf-9c8a-963b0e6c6b9f/link' \
--header 'Content-Type: application/json' \
--header 'X-Retailer-Id: the-garden' \
--header 'Authorization: Bearer <access_token>' \
--data-raw '{
  "linking_token": "l0ebkrG2JAXEuNI9UBpWXO-yC7asltvuyw4RjELk3Hc"
}'

The accounts are now linked.
