#SPEI

Plan SPEI account plugin activation for Mexico.

#Overview

SPEI is Mexico's interbank electronic payment system operated by Banco de México. It enables near-real-time transfers between bank deposit accounts.

The Bloque SDK does not expose a public accounts.spei client yet. Treat this page as the format and activation guide for teams preparing a SPEI rollout with Bloque.

#Supported Formats

For SPEI payments, Banco de México describes the beneficiary account identifier as one of the following formats:

CLABE is the primary format to plan around for account plugins.

#CLABE Structure

The CLABE is an 18-digit numeric identifier:

The control digit validates the CLABE structure, but it does not prove that the account exists or is active.

#Activation Checklist

Before scheduling the sales call, prepare:

• target entity type and country configuration for Mexico
• expected use case: receive, payout, reconciliation, or treasury movement
• supported beneficiary identifiers: CLABE only, or CLABE plus debit card/mobile
• webhook and receipt requirements, including CEP reconciliation needs
• compliance status for the holders that will use the rail

#Example

Use this pattern to prepare the information needed for activation. The full example is available at examples/accounts/spei/prepare-spei-plugin.ts.

type SpeiIdentifierType = 'CLABE' | 'DEBIT_CARD' | 'MOBILE';

const activationUrl = 'https://calendly.com/hi-bloque/15-min';

const request = {
  rail: 'spei',
  activationUrl,
  country: 'MEX',
  useCase: 'receive',
  requestedIdentifierTypes: ['CLABE'] satisfies SpeiIdentifierType[],
  sampleIdentifier: {
    type: 'CLABE' satisfies SpeiIdentifierType,
    value: '002010077777777771',
  },
  webhookUrl: 'https://api.example.com/webhooks/spei',
};

console.log('SPEI activation request:', request);
console.log('Schedule activation:', activationUrl);
