Glossary
Definitions of Bre-B terms — payment key, target, tenant account, and more.
A short alphabetical reference for the terms you will encounter while integrating Bre-B Participant. Each entry is a one or two sentence plain-language definition. For the full data model behind any of these, follow the link to the corresponding concept page.
This glossary is a starting point and will grow. If a term you need is missing, please open an issue on the docs repo so we can add it.
Bre-B
Colombia's interbank instant-payment scheme — a real-time, 24/7 rail similar to Brazil's Pix or India's UPI.
Central directory
The Bre-B-operated registry that maps payment keys to holder identity and destination bank. Every resolution query goes against the central directory.
Collection
An incoming Bre-B payment to one of your tenant accounts. You receive collections by displaying a Bre-B QR code or otherwise sharing a payment key.
EDE (Entidad de Depósito Electrónico)
A Colombian regulatory category for licensed deposit-taking entities. Many Bre-B participants are EDEs.
Outgoing transfer
A Bre-B payment your tenant initiates against another participant's payment key.
Participant
A bank or licensed entity authorized to transact on Bre-B. Mono offers Bre-B participant access through its API.
Payment key
An alias that identifies a destination on Bre-B — a phone number, document ID, email, an alphanumeric Bre-B-issued identifier, or a merchant code. Used for both sending (you specify the destination key) and receiving (your tenant has registered keys).
QR (Bre-B QR)
An EMVCo-compliant QR code encoding a Bre-B payment instruction. Customers scan it from their banking app to authorize a transfer.
Resolution
The process of looking up a payment key against the central directory to obtain the holder's name and bank before dispatching an outgoing transfer.
Target
The resolved destination of an outgoing transfer. Returned by a successful resolution and required to dispatch.
Tenant account
A logical account at Mono that holds balances and is the source/destination of Bre-B operations.
Webhook signature
An HMAC-SHA256 signature attached to every Bre-B webhook so you can verify the payload came from Mono. See Webhook signatures.
