Metadata Guide

​

Introduction

​

Overview

• Metadata keys can be up to 40 characters long
• Metadata values can be up to 500 characters long
• You can have up to 50 metadata key-value pairs per object
• Keys should only contain alphanumeric characters, dashes, and underscores
• Metadata is not searchable using our API but is returned in API responses and webhooks

​

Use Cases

• Storing external IDs or references
• Adding internal annotations
• Linking Dodo Payments objects to your system
• Categorizing transactions
• Adding custom attributes for reporting

​

Adding Metadata

// Adding metadata when creating a payment
const payment = await client.payments.create({
    billing: { city: 'city', country: 'AF', state: 'state', street: 'street', zipcode: 0 },
    customer: { customer_id: 'customer_id' },
    product_cart: [{ product_id: 'product_id', quantity: 0 }],
    metadata:{order_id: 'ORD-123', customer_notes: 'Customer notes'}
  });

​

Retrieving Metadata

const payment = await client.payments.retrieve('pay_123');
console.log(payment.metadata.order_id); // '6735'

​

Searching and Filtering

1. Store important identifiers in metadata
2. Retrieve objects using their primary IDs
3. Filter the results in your application code

// Example: Find a payment using your order ID
const payments = await client.payments.list({
  limit: 100
});

const matchingPayment = payments.data.find(
  payment => payment.metadata.order_id === '6735'
);

​

Best Practices

​

Do:

• Use consistent naming conventions for metadata keys
• Document your metadata schema internally
• Keep values short and meaningful
• Use metadata for static data only
• Consider using prefixes for different systems (e.g., crm_id, inventory_sku)

​

Don’t:

• Store sensitive data in metadata
• Use metadata for frequently changing values
• Rely on metadata for critical business logic
• Store duplicate information that’s available elsewhere in the object
• Use special characters in metadata keys

​

Supported Objects

​

Webhooks and Metadata

// Example webhook handler
app.post('/webhook', (req, res) => {
  const event = req.body;

  if (event.type === 'payment.succeeded') {
    const orderId = event.data.object.metadata.order_id;
    // Process order using your internal order ID
  }
});
