VM0033 API Workthrough

Below is complete API flow to execute Verra VM0033 Methodology:

1. Policy Preparing from Standard Registry (SR) side:

1.1 Login by SR

To login, the user must request a refresh token:

POSThttp://localhost:4200/api/v1/accounts/login/ with credentials in body:

   {
      "username":"StandardRegistry",
      "password":"test"
   }

Successful response looks like:

{
   "username": "StandardRegistry",
   "did": "did:hedera:testnet:83JSEFhdaoZ4ougdVtCpAWXbsCP8hcuNpSZeEJ8GSins_0.0.6851752",
   "role": "STANDARD_REGISTRY",
   "refreshToken": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9eyJpZCI6ImY0MGZiMDIzLWNlMzUtNDFmYS1hNzAxLTkyYjdmMmQ1MzQ5MiIsm5hbWUiOiJTdGFuZGFyZFJlZ2lzdHJ5IiwiZXhaXJlQXQiOjE3ODk0ODAxMzU2NTQsImlhdCI6MTc1Nzk0NDEzNX0Lr10b-in9SlAgTvKLwdypOVY8uANlAEJ1zNduHK8OpTxIUS-dBZ39OAZyr4sQRqsJYkxtRAiItYOgS45EvPBP1u-XMAzS2CqeM2lu2N81k53Sy6RQrDmpK_YIDMmRWeWMulJJ5IWtSe3kga4hwbYs0SyTXRkuVfoG-SnAlmTgA",
   "weakPassword": false
}

With the refreshToken from the response, you can obtain an access token, which is then used in the authorization header for each request:

POST http://localhost:4200/api/v1/accounts/access-token/

{
   "refreshToken":"eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9. eyJpZCI6Ijc4NWRmODljLTY2OTQtNGIwMC04OWRlLTllZjJkMjZkY2RmZiIsIm5hbWUiOiJTdGFuZGFyZFJlZ2lzdHJ5IiwiZXhwa XJlQXQiOjE3ODk0ODAwNjg5NDAsImlhdCI6MTc1Nzk0NDA2OH0.

}

Successful response looks like:

1.4 Assign Policy to VVB and Project Proponent (PP) Users

To assign a policy to a user, include the username in the request body, and set the policyId field to the id value from the policy importing step:

POST http://localhost:4200/api/v1/permissions/users/{username}/policies/assign/

For example:

POST http://localhost:4200/api/v1/permissions/users/ProjectProponent/policies/assign/

POST http://localhost:4200/api/v1/permissions/users/VVB/policies/assign/

with body, where in policyId using "id" field from policy importing step:

{
   "policyIds":["68c952870fd12e530dddadf8"],
   "assign":true
}

Successful response looks like:

   true

2. Token associate and grant KYC

2.1 Login as SR

2.1.1 Associate Token for PP

Before associating, obtain the tokenId by extracting it from the token linked to the policy:

GET http://localhost:4200/api/v1/tokens

Successful response looks like:

   [
      {
         "id":"68c819368a003cc1fb32e9b6",
         "tokenId":"0.0.6851817",
         "tokenName":"VCU",
         "tokenSymbol":"VCU",
         "tokenType":"non-fungible",
         "decimals":0,
         "policyId":null,
         "enableAdmin":true,
         "enableFreeze":true,
         "enableKYC":true,
         "enableWipe":true,
         "associated":false,
         "balance":null,
         "hBarBalance":null,
         "frozen":null,
         "kyc":null,
         "policies":["VM0033-v1.0.3_8_14_1755731415625 (1.2.5)"],
         "policyIds":["68c952870fd12e530dddadf8"],
         "canDelete":false
      }
   ]

We need to extract tokenId from token, which linked with our policy(policyId from step 1.2 equal with policyIds in response)

Send a request with the tokenId from the previous response:

PUT http://localhost:4200/api/v1/tokens/0.0.6851817/associate

Successful response looks like:

   {
      "tokenName":"VCU",
      "status":true
   }

2.3 Login by PP

2.3.1 Grant KYC Token by PP

To grant a KYC token, send a request with the tokenId and the username:

PUT http://localhost:4200/api/v1/tokens/0.0.6851817/ProjectProponent/grant-kyc

Successful response looks like:

   {
      "id":"68c819368a003cc1fb32e9b6",
      "tokenId":"0.0.6851817",
      "tokenName":"VCU",
      "tokenSymbol":"VCU",
      "tokenType":"non-fungible",
      "decimals":0,
      "policyId":null,
      "enableAdmin":true,
      "enableFreeze":true,
      "enableKYC":true,
      "enableWipe":true,
      "associated":true,
      "balance":"0",
      "hBarBalance":"4.78479825 ℏ",
      "frozen":false,
      "kyc":true
   }

3 Register PP in policy and create project description

3.1 Login by PP

3.2 Choose PP Role in Policy and Create Project Description

To choose a role in the policy, send a request with the role name in the body:

POST http://localhost:4200/api/v1/policies/68c952870fd12e530dddadf8/tag/Choose_Roles/blocks/

with body:

   {
      "role":"Project_Proponent"
   }

Successful response looks like:

true

To create a project description in the policy, send a request with the project description details. (The payload example is large and will be attached separately.):

POST http://localhost:4200/api/v1/policies/68c952870fd12e530dddadf8/tag/add_project_bnt/blocks/

body: {
   "document": *payload from file*,
