Introduction
Context memory

Every conversation in Kindly has its own key-value store named context that serves as the bot's memory for that conversation.
Saving values
The bot can collect information from the user via Pattern dialogues﻿. In addition, if the bot sends a Webhooks reference﻿ to another service, the response from the webhook service can contain new context as well.
Keep in mind that the context memory is a simple key-value storage. If you insert a key-value pair where the key already exists in the memory, the value will be overwritten and the old value will be lost.
Retrieving values
When defining bot replies, you may insert placeholders that look like {key}. If key is found in the chat context, the value will be inserted. If key is not available, the bot will not use that reply, but try to find something else to reply with, or go to a fallback reply.
The full context is also sent with every Webhooks reference﻿, allowing you to perform any operation you'd like on the context data in your own service.
Managing context via API
If you're using Application API﻿, you can also read and write to the context storage with your API requests.
Writing to context
When you send data, you can send new_context which will be merged with any existing context for the chat. If you send a key-value pair where the key already exists, the value will be overwritten. If the key does not exist the key-value pair will be inserted (upsert strategy).
Example:
Shell
curl \
  -H 'Content-Type: application/json' \
  -H "Authorization: YOUR_API_KEY" \
  -d '{"user_id": "UNIQUE_USER_ID", "message": "Hello world!", "new_context": {"key": "value"}}' \
  https://bot.kindly.ai/api/v1/send
curl \
  -H 'Content-Type: application/json' \
  -H "Authorization: YOUR_API_KEY" \
  -d '{"user_id": "UNIQUE_USER_ID", "message": "Hello world!", "new_context": {"key": "value"}}' \
  https://bot.kindly.ai/api/v1/send

Reading context
When you receive a message from the bot, you will also find the context is attached as part of the JSON payload.
Example:
JSON
{
  "message": "Hello world!",
  "context": {
    "key": "value"
  }
}
{
  "message": "Hello world!",
  "context": {
    "key": "value"
  }
}

Set context in Kindly Chat
In some cases you might want to add data to the chat context on Kindly Chat initialization, for instance to know on which page the chat client is loaded or the email of a logged in user.
You can set chat context when initializing the chat client by populating window.kindlyOptions.context before loading the Kindly Chat HTML snippet:
HTML
<script>
  window.kindlyOptions = {
    context: {
      email: "[email protected]",
      url_path: "/interesting-product-slug"
    }
  };
</script>
<script
  id="kindly-chat"
  src="https://chat.kindlycdn.com/kindly-chat.js"
  data-bot-key="YOUR-BOT-KEY"
  async
></script>
<script>
  window.kindlyOptions = {
    context: {
      email: "user@example.com",
      url_path: "/interesting-product-slug"
    }
  };
</script>
<script
  id="kindly-chat"
  src="https://chat.kindlycdn.com/kindly-chat.js"
  data-bot-key="YOUR-BOT-KEY"
  async
></script>
