API Handler

The outgoing request (from BitBadges to your plugin) will be made up of the custom body inputs (passed from your frontend), the claim parameters, plus some contextual information about the claim and the claiming user.

• Plugin Secret: A plugin secret value that you can use to verify BitBadges as the origin of the call. This is secret only to you and can be obtained via the developer portal when creating your plugin.

• Claiming Address: The bitbadgesAddress of the user who is attempting to claim. We also provide the mapped equivalents (ethAddress, etc).

• Claim Information: Lastly, we also pass the claimId, as well as the claim's createdAt and lastUpdated timestamps. These can be used, for example, to implement version control systems on your end.

• Claim Attempt ID: The claim attempt ID is the ID of the attempt, and you can use it to track the status of the claim (whether it eventually fails or succeeds).

• Attempt Status: The attempt status (attemptStatus) will be 'executing' during the execution of the claim. If you subscribe to success status webhooks (in the configuration), we will also send a second request (with same body and headers) and _attemptStatus='success'. This can be used to trigger post-claim logic that needs to wait until completion.

• Simulation (Dry Run) Flag: The _isSimulation flag tells you whether this is a known dry run.

For POST, PUT, and DELETE requests, we pass the values over the body. For GET, we pass them over the GET params. You are responsible for making sure the endpoint is accessible (e.g. no CORS errors, etc.). Make sure it is the desired type as well (i.e. GET vs POST vs DELETE vs PUT).

const payload = {
    ...customBody, //if applicable
    ...allConfiguredParams, //if applicable

    // Context info

    email: { id: '[e-mail]' }, //If pass email is configured
    discord: { id: '...', username: '...', discriminator: '...' }, //If configured
    twitch: { id: '...', username: '...' }, //If configured
    twitter: { id: '...', username: '...' }, //If configured
    github: { id: '...', username: '...' }, //If configured
    google: { id: '...', username: '...' }, //If configured
    pluginSecret: pluginDoc.pluginSecret,
    claimId: context.claimId,
    claimAttemptId: context.claimAttemptId,
    bitbadgesAddress: context.bitbadgesAddress, //If pass address is configured
    ethAddress: context.ethAddress, //If pass address is configured
    solAddress: context.solAddress, //If pass address is configured
    btcAddress: context.btcAddress, //If pass address is configured
    _attemptStatus: context._attemptStatus,
    lastUpdated: context.lastUpdated,
    createdAt: context.createdAt,
    version: context.version,
};

Responses

All responses expect a 200 success OK status code within 10 seconds for a successful attempt. For any of the below, do not assume that a 200 OK response means a successful claim and a successful set of the new state. Think of this as a hypothetical state transition IF the claim is eventually successful.

Note: Ensure the returned JSON object keys do not contain any "." characters because that may mess up the state handler. For example, emails should be bob@abc[dot]com rather than [e-mail].

Stateless Preset

The stateless preset is simple. If we receive the 200, the plugin is successful. Nothing else is checked via the response. Everything is handled on your end (if you have state).

Claim Token Preset

This preset expects a { claimToken} in the response. The claim token is a one-time use only claim code. Issuing claim tokens is left up to you.

Claim Numbers Preset

This preset expects a { claimNumber } in the response. The claim number is the claim number that will be assigned if the claim number is successful. Claim numbers are 0-based, so claimNumber === 0 is the first claim, and so on.

IMPORTANT: Only one plugin can control claim number assignment. If you select this approach, claims that use this plugin will not be compatible with any other plugin that uses the claim number preset.

Another important decision you will have to consider is whether to reuse your plugin for address lists because claim numbers do not matter for address list plugins. So basically, your plugin will function like the stateless preset for address list claims, if selected.

Success Hook Responses

For success hooks (_attemptStatus=success), we also expect a 200 OK within 10 seconds. If you need to do asynchronous processing, return 200 OK early and process as you desire.

Otherwise, for failed attempts, we will retry later with an exponential backoff policy.

Error Responses

If your plugin fails, we will save the error for debugging / monitor purposes. It may be displayed to the claiming user and / or claim cretor, so make errors informative but do not reveal sensitive information.

Please follow the { message } interface for returned JSON error responses.

Example Plugin Handler

//TODO: Fill in missing information
const handlePlugin = async (req: NextApiRequest, res: NextApiResponse) => {
  try {
    //Step 1: Handle the request payload from the plugin
    const body = req.body; //We assume the plugin sends the payload in the body of the request (change this for GET)
    const { claimId, pluginSecret, bitbadgesAddress, ethAddress, solAddress, btcAddress, lastUpdated, createdAt } = body;
    const { ...otherCustomProvidedInputs } = body;
    
    //Handle anything specific to dry runs _isSimulation

    //Step 2: Verify BitBadges as origin by checking plugin secret is correct
    const YOUR_PLUGIN_SECRET = '';
    if (pluginSecret !== YOUR_PLUGIN_SECRET) {
      return res.status(401).json({ message: 'Invalid plugin secret' });
    }

    //Step 3: Implement your custom logic here. Consider checking the plugin's creation / last updated time to implement version control.
    //TODO: 

    //Step 4: Return the response to the plugin based on your configured state function preset
    // const claimTokenRes = { claimToken: '...'  }
    // const statelessRes = {};
    return res.status(200).json({});
  } catch (err) {
    console.log(err);
    return res.status(401).json({ message: `${err}` });
  }
};

export default handlePlugin;
