Error Handling

Both TypeScript and Python SDKs provide comprehensive error handling capabilities. The base error class is FathomError for both SDKs.

​
Basic Error Handling

import { Fathom } from 'fathom-typescript';
import * as errors from 'fathom-typescript/models/errors';

const fathom = new Fathom({
  security: {
    apiKeyAuth: "YOUR_API_KEY"
  }
});

try {
  const result = await fathom.listMeetings({});
  for await (const page of result) {
    console.log(page);
  }
} catch (error) {
  if (error instanceof errors.FathomError) {
    console.log(error.message);
    console.log(error.statusCode);
    console.log(error.body);
    console.log(error.headers);
  }
}

​
Handle Specific Status Codes

import { Fathom } from 'fathom-typescript';
import * as errors from 'fathom-typescript/models/errors';

async function handleSpecificErrors() {
  const fathom = new Fathom({
    security: {
      apiKeyAuth: "YOUR_API_KEY"
    }
  });

  try {
    const result = await fathom.listMeetings({});
    return result;
  } catch (error) {
    if (error instanceof errors.FathomError) {
      switch (error.statusCode) {
        case 401:
          console.log("Authentication failed. Check your API key.");
          break;
        case 403:
          console.log("Access forbidden. Check your permissions.");
          break;
        case 404:
          console.log("Resource not found.");
          break;
        case 429:
          console.log("Rate limit exceeded. Try again later.");
          break;
        default:
          if (error.statusCode >= 500) {
            console.log("Server error. Try again later.");
          } else {
            console.log(`Unexpected error: ${error.message}`);
          }
      }
    }
    return null;
  }
}
