Who is waiting
Maya Okafor, support lead at Acme Ltd, asked who had messaged on WhatsApp this morning. Memtro listed recent conversations with the last message's direction, channel and time, so she could see which ones were waiting on a reply.
Sinch + Memtro
Who messaged us on WhatsApp today, and on which channels?
Sinch shows your messaging traffic across SMS, RCS, WhatsApp, Viber, Messenger and other channels. You see the project's apps and channels, message history by contact, conversation, channel, direction and time, recent conversations, and contacts looked up by external id or phone number. When asked and granted, Memtro can send a text message, create, merge or delete contacts, stop or delete conversations and delete messages. Sinch can tell Memtro when a contact sends a message, a delivery receipt arrives or a contact opts out, and a job can start on it. Message text and phone numbers are never returned.
In Memtro
What you can do with Sinch in Memtro
Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right Sinch tool, reads what it needs, and answers with the source cited.
What it does
- 01See message history by app, contact, conversation, channel, direction and time, without text or numbers.
- 02List recent conversations with the last message's direction, channel and time.
- 03Look up a contact by your external id or a phone number, with language and channels.
- 04Check the project's apps and the channels each has configured.
- 05When asked and granted, send a text message to a contact or number, delivered for real and charged per message.
- 06With events on, an inbound message, a delivery receipt or a contact opting out in Sinch can start a job.
Acts when asked
When you ask it to
These tools change something in Sinch. The model is told to use them only when you ask for exactly that, and an administrator grants each one by name to the teams that may use it; a personal connection acts only after its owner allows it.
- 01Send a text message to a contact or phone number (spends Sinch credit)
- 02Create a contact
- 03Merge two contacts (the source contact is removed)
- 04Delete a contact
- 05Stop an active conversation
- 06Delete a conversation and its messages
- 07Delete a message
Events
When it happens
Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with Sinch for you. Each event can start a job, with the event as its input. Sinch signs every delivery, and one whose signature does not check out is refused before it is read.

In practice
Ask it like you would a colleague
Once Sinch is connected, these are the kinds of things people ask. Plain questions, no syntax. If the answer lives partly in another system you have connected, Memtro looks there too.

At Northwind, a job starts when Sinch reports a contact opted out. Memtro looks up the contact and its conversations, then tells Dan Fletcher, the CRM owner, which external id to stop messaging.

FAQ
Questions
Can Memtro change anything in Sinch?+
Only when you ask, and only what it has been granted: send a text message to a contact or phone number (spends Sinch credit); create a contact; merge two contacts (the source contact is removed); delete a contact; stop an active conversation; delete a conversation and its messages; delete a message. Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.
Who can use a Sinch connection?+
A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.
Does Memtro store my Sinch data?+
Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded.
How do I connect Sinch?+
Region, Project ID, Access key ID and Access key secret. In dashboard.sinch.com, copy the project's UUID from Conversation API, then Apps, and create an access key for the project under Settings, then Access keys.
Can Sinch start a job?+
Yes. Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with Sinch for you. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
