Implementation Reference

• src/handlers/webhooks.ts:57-96 (handler)

  The core handler function that validates input using isFetchWebhooksByCampaignParams, creates a SmartLead API client, makes a GET request to `/campaigns/${campaign_id}/webhooks` with retry logic, and returns the response data or error.

  async function handleFetchWebhooksByCampaign(
    args: unknown,
    apiClient: AxiosInstance,
    withRetry: <T>(operation: () => Promise<T>, context: string) => Promise<T>
  ) {
    if (!isFetchWebhooksByCampaignParams(args)) {
      throw new McpError(
        ErrorCode.InvalidParams,
        'Invalid arguments for smartlead_fetch_webhooks_by_campaign'
      );
    }
  
    try {
      const smartLeadClient = createSmartLeadClient(apiClient);
      const { campaign_id } = args;
      
      const response = await withRetry(
        async () => smartLeadClient.get(`/campaigns/${campaign_id}/webhooks`),
        'fetch webhooks by campaign'
      );
  
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(response.data, null, 2),
          },
        ],
        isError: false,
      };
    } catch (error: any) {
      return {
        content: [{ 
          type: 'text', 
          text: `API Error: ${error.response?.data?.message || error.message}` 
        }],
        isError: true,
      };
    }
  }

• src/tools/webhooks.ts:6-20 (schema)

  Defines the tool metadata: name, description, ToolCategory.WEBHOOKS, and input schema requiring 'campaign_id' string.

  export const FETCH_WEBHOOKS_BY_CAMPAIGN_TOOL: CategoryTool = {
    name: 'smartlead_fetch_webhooks_by_campaign',
    description: 'Fetch all the webhooks associated with a campaign using the campaign ID.',
    category: ToolCategory.WEBHOOKS,
    inputSchema: {
      type: 'object',
      properties: {
        campaign_id: {
          type: 'string',
          description: 'ID of the campaign to fetch webhooks for',
        },
      },
      required: ['campaign_id'],
    },
  };

• src/index.ts:221-224 (registration)

  Conditionally registers all webhook tools (including smartlead_fetch_webhooks_by_campaign) via toolRegistry.registerMany(webhookTools) if webhooks category is enabled.

  // Register webhook tools if enabled
  if (enabledCategories.webhooks) {
    toolRegistry.registerMany(webhookTools);
  }

• src/types/webhooks.ts:49-56 (schema)

  Runtime type guard for validating input arguments match FetchWebhooksByCampaignParams interface (campaign_id: string), used in the handler.

  export function isFetchWebhooksByCampaignParams(args: unknown): args is FetchWebhooksByCampaignParams {
    return (
      typeof args === 'object' &&
      args !== null &&
      'campaign_id' in args &&
      typeof (args as FetchWebhooksByCampaignParams).campaign_id === 'string'
    );
  }
