# Mailchimp

<p>Create a Mailchimp Marketing API key from Account &gt; Extras &gt; API keys. Its final suffix (for example -us21) identifies the data center: enter <a href="https://us21.api.mailchimp.com/">https://us21.api.mailchimp.com</a> as base URL and the entire key in this connection. This uses Marketing API v3.0 and is separate from Mandrill/Transactional. Start with account.get and audiences.list. Member creation requires appropriate marketing consent; pending requests double opt-in and can send a confirmation email. No campaign sending or bulk enrollment is included. One explicit request/page per invocation; no retries, automatic pagination or background work. This is a documented common-command subset, not the full provider API.</p>

<h2>Connect and use</h2>

<p><a href="https://www.tooluse.net/tools/integrations/mailchimp">Connect and use</a></p>
<p>Open the integration&#39;s connection form to check the available credential source. The source has not been resolved for this documentation export. The instructions below apply when using your own provider account.</p>
<h2>Get your provider credentials</h2>
<p>Follow these steps for Mailchimp, then enter the issued values in the connection form below.</p>
<ol>

</ol>
<p><a href="https://mailchimp.com/help/about-api-keys/">Official credential setup</a></p>
<h2>Where to enter credentials</h2>
<p>In the integration page, sign in, choose your workspace and open Connect. If a <strong>Credentials</strong> choice is shown, select <strong>Use my credentials</strong>. Fill the following connection fields and save. Provider credentials belong in this form, never in an MCP configuration or tool input.</p>

</div><p>Open API keys and create a Tooluse.net key for the enabled commands.</p>
<p>Set TOOLUSE_API_KEY in your client and use the shared MCP configuration.</p>
<p><a href="https://help.tooluse.net/clients">Configure Claude Code, Codex or Cursor once</a></p>

<h2>Permissions and results</h2>

<p>If you have more than one workspace, check the selected workspace in the connection or API-key dialog before saving. Roles, enabled commands, expiry and revocation use Tooluse.net&#39;s existing permissions. Disabling a connection or revoking a key immediately prevents new calls.</p>

<p>Send one Claude tool_use block per request. Keep the same Idempotency-Key when retrying the same request; use a new key for a new call. The response includes the shared Tooluse.net receipt and Claude tool_result. Check both HTTP status and the returned tool result before treating a call as successful.</p>

<p>Your connection&#39;s daily allowance and key permissions also apply. Adding a connection does not make a provider request.</p>

<p>Calls return the shared execution receipt and a Claude tool_result. Provider output varies by operation; consult the provider documentation for its response fields. Unconfirmed calls should be checked before retrying.</p>

<h2>Call from your client</h2>

<p>Use the shared MCP configuration. Refresh your client&#39;s tool list after saving the connection or changing key permissions, then call the returned tool name with the example input below.</p>

<p><a href="https://help.tooluse.net/clients">Configure Claude Code, Codex or Cursor once</a></p>

<h2>Discover your enabled tools</h2>

<p>List permitted tools in Claude format. Read every page using page and size (maximum 100) until all results have been received. Use the returned name, not a catalog capability identifier, in the tool_use block.</p>

<pre><code class="language-bash">curl 'https://api.tooluse.net/v1/tools' \
  -H "Authorization: Bearer $TOOLUSE_API_KEY"
</code></pre>

<p>Find this command in the tool list permitted by your key. Replace svc_FROM_YOUR_TOOL_LIST with its returned name. Use a new Idempotency-Key for each new call and retain it when retrying that same call.</p>

<h2>HTTP call</h2>

<pre><code class="language-bash">curl 'https://api.tooluse.net/v1/tool-calls' \
  -H "Authorization: Bearer $TOOLUSE_API_KEY" \
  -H 'Content-Type: application/json' \
  -H 'Idempotency-Key: replace-with-a-new-call-id' \
  --data '{
  "type": "tool_use",
  "id": "toolu_example",
  "name": "svc_FROM_YOUR_TOOL_LIST",
  "input": {}
}'
</code></pre>

<p>Send one Claude tool_use block per request. Keep the same Idempotency-Key when retrying the same request; use a new key for a new call. The response includes the shared Tooluse.net receipt and Claude tool_result. Check both HTTP status and the returned tool result before treating a call as successful.</p>

<h2>Errors</h2>

<p>Check the key&#39;s expiry, revocation, workspace and allowed operations.</p>

<p>Reuse the same idempotency key only for the same request.</p>

<p>The connection or provider limit has been reached. Check the receipt before retrying.</p>

<h2>Test the connection</h2>

<p>Open the integration&#39;s commands below to inspect parameters and examples. Start with a read command for an account or resource you can access. Refresh your client&#39;s tool list, use the returned tool name, and check the execution result and usage. Provider charges and permissions still apply. Never test a write against production data without reviewing it.</p>
