Current channels on one platform

Telegram and MAX messengers are currently available. The unified API contract is designed to support other messengers and SMS. As the platform evolves, communication channels will be added automatically without requiring additional integration

The MassAccess platform is available in two deployment options: SaaS and On-premise. The same per-message price applies regardless of the option you choose

One integration for all channels

Integrate MassAccess once and use the available communication channels through a unified API. MassAccess handles the integration specifics for each channel.

When new channels become available, your product's core integration with MassAccess remains unchanged.

A customer's phone number alone is not enough to start a conversation with the bot. First, the customer must register their contact through your bot according to its flow. You can then send messages to the bot using the customer's phone number
curl -X POST https://massaccess.net/api/v1/send \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"phone_number":"01234567890","message":"Order ready"}'

Frequently asked questions

Can I message any phone number?

No. The recipient must first open your company bot, start its flow, and share their contact.

Is on-premise fully offline?

No. It requires outbound access to MassAccess for licensing, metering, and cloud billing.

Will new channels require integration changes?

Channel setup differs, but your service uses the unified MassAccess API. New messengers and SMS will be added as adapters to the same contract.
