name	memberstack-admin-api
description	Work with the Memberstack Admin API to manage members, plans, and data tables. Use this skill whenever the user mentions Memberstack, member management via API, Memberstack data tables, or wants to build integrations that create/read/update/delete members or data records in Memberstack. Also trigger when the user asks about Memberstack API endpoints, authentication, pagination, querying records, or connecting plans to members — even if they don't say "Memberstack" explicitly but reference concepts like plan connections, member metadata, or admin member APIs that align with Memberstack's domain.

Memberstack Admin API Skill

This skill provides guidance for interacting with the Memberstack Admin API. It covers two core domains: Member management and Data Tables.

Quick Start

All requests require an API key passed via header:

x-api-key: YOUR_API_KEY

Base URL: https://admin.memberstack.com

Data Tables endpoints use the /v2/ prefix; Member endpoints do not.

API Key Handling

Never ask the user for their API key directly in the conversation. API keys are sensitive credentials and should never appear in chat, code snippets shown to the user, or be hardcoded in source files. Instead:

• Store the key in a .env file (e.g., MEMBERSTACK_API_KEY=sk_...) and read it via process.env.MEMBERSTACK_API_KEY (Node) or os.environ["MEMBERSTACK_API_KEY"] (Python).
• Alternatively, use the platform's secrets/environment variable management (e.g., Vercel Environment Variables, Cloudflare Secrets, AWS Secrets Manager).
• When generating code, always reference the key from an environment variable, never use a placeholder that looks like a real key.
• If the user pastes an API key in the chat, remind them to rotate it and move it to a .env file or secret store instead.

When to Read Reference Files

This skill bundles the full API reference docs. Read them based on what the user needs:

• Member operations (list, get, create, update, delete, add/remove plans): Read references/memberstack-member-actions.md

• Data Tables (list tables, get table schema, create/update/delete/query records): Read references/memberstack-data-tables.md

If the task involves both members and data tables, read both files.

API Overview

Members API

Endpoints for managing members, their profiles, plan connections, and metadata.

Action	Method	Endpoint
List members	GET	/members
Get member	GET	/members/:id_or_email
Create member	POST	/members
Update member	PATCH	/members/:id
Delete member	DELETE	/members/:id
Add free plan	POST	/members/:id/add-plan
Remove free plan	POST	/members/:id/remove-plan

Key concepts:

• Member IDs start with mem_, plan IDs with pln_, connection IDs with con_
• Members can be looked up by ID or URL-encoded email
• Pagination uses cursor-based after + limit (max 200)
• Members have customFields, metaData, json, permissions, and planConnections

Data Tables API

Endpoints for managing structured data with typed fields, relationships, and querying.

Action	Method	Endpoint
List tables	GET	/v2/data-tables
Get table	GET	/v2/data-tables/:tableKey
Create record	POST	/v2/data-tables/:tableKey/records
Update record	PUT	/v2/data-tables/:tableKey/records/:recordId
Delete record	DELETE	/v2/data-tables/:tableKey/records/:recordId
Query records	POST	/v2/data-tables/:tableKey/records/query

Key concepts:

• Tables are referenced by key (e.g., products) or ID (e.g., tbl_...)
• Records hold data as key-value pairs matching field definitions
• Querying supports findMany and findUnique with rich filtering (equals, contains, gt, lt, in, logical operators AND/OR/NOT)
• Pagination via take (max 100), skip, or cursor-based after
• Field types include TEXT, NUMBER, DECIMAL, BOOLEAN, DATE, EMAIL, URL, REFERENCE, and MEMBER_REFERENCE variants

Common Patterns

Paginating Through All Members

let allMembers = [];
let cursor = undefined;
let hasMore = true;

while (hasMore) {
  const params = new URLSearchParams({ limit: '200' });
  if (cursor) params.set('after', cursor);

  const res = await fetch(`https://admin.memberstack.com/members?${params}`, {
    headers: { 'x-api-key': API_KEY }
  });
  const json = await res.json();

  allMembers.push(...json.data);
  hasMore = json.hasNextPage;
  cursor = json.endCursor;
}

Querying Data Records with Filters

const res = await fetch(
  'https://admin.memberstack.com/v2/data-tables/products/records/query',
  {
    method: 'POST',
    headers: {
      'x-api-key': API_KEY,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      query: {
        findMany: {
          where: {
            AND: [
              { price: { gte: 10 } },
              { inStock: { equals: true } }
            ]
          },
          orderBy: { price: 'asc' },
          take: 50
        }
      }
    })
  }
);

Creating a Member with a Plan

const res = await fetch('https://admin.memberstack.com/members', {
  method: 'POST',
  headers: {
    'x-api-key': API_KEY,
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    email: '[e-mail]',
    password: 'securePassword123',
    plans: [{ planId: 'pln_abc123' }],
    customFields: { firstName: 'Jane', country: 'Australia' }
  })
});

Error Handling

The API returns errors as JSON with code and message fields. Common status codes:

• 400: Bad request (missing required fields, invalid formats, empty data)
• 404: Resource not found (wrong table key, nonexistent member/record)

Always check for these and surface clear messages to the user.

Tips

• When deleting members, consider setting deleteStripeCustomer and cancelStripeSubscriptions to avoid orphaned billing records.
• Use findUnique with where.id when you know the exact record ID — it's simpler and returns a single record.
• The _count option in findMany is useful for getting totals without fetching all records.
• select and include are mutually exclusive in queries — use include to expand relationships, select to limit returned fields.
