Business Messaging API
A REST or programmatic interface businesses use to send messages from their backend — like Tody’s Business API — without using a consumer chat app.
Glossary
Plain-language glossary of messaging & compliance terms
Terms that show up across the Tody docs and the broader Indian messaging industry — explained without jargon.
Idempotency key
A unique key sent with an API request so retries don’t create duplicate messages. Tody honours idempotency keys within a 24-hour window.
HMAC webhook signature
A signed hash sent with each webhook payload, so the receiver can verify the message really came from Tody and was not modified in transit.
Template approval
The review process where a business’s message templates are checked for compliance with category rules (transactional, promotional, utility) before they can be used in production.
Audit log
A record of every important platform action — template changes, campaigns, key issuance, wallet movements — that can be exported for compliance review.
India data residency
A commitment that customer data is stored and processed inside Indian data centres, not moved cross-border without explicit consent.
Wallet billing
A prepaid balance that is debited per message sent. The opposite of fixed monthly subscriptions. Tody&rsquo>s Business API uses wallet billing.
Sender identity
The verified business identity associated with outbound messages, as opposed to anonymous or pooled sender numbers.
Rate limit
A cap on how many API requests a key can make per unit of time, to protect the platform and downstream recipients.
BSP (Business Solution Provider)
A reseller / aggregator that delivers messages on behalf of a business through a parent network. Tody is the network itself, not a BSP.
DPDP Act
The Digital Personal Data Protection Act, 2023 — India’s data protection law that governs how personal data is collected, processed, and stored.
DSAR (Data Subject Access Request)
A request from a person to access, correct, or erase their personal data held by a platform.
