+Users can communicate with RapidPro by creating an Interactive chatbots in IoGT.
+
+## Create a service account in IoGT
+
+RapidPro needs a service account within IoGT to be able to authenticate itself to IoGT and establish communication. The service account is set up within IoGT as an unprivileged user account within a specific user group. Any Wagtail Admin should be able to set up the service account manually.
+
+- Create a new group (_Settings_ > _Groups_, _Add a group_)
+  - The name must be exactly 'rapidpro_chatbot'
+  - No permissions are required
+- Create the service account (_Settings_ > _Users_, _Add a user_)
+  - The username just has to be unique
+  - Use a long and varied password (no need to remember it)
+  - It is recommended to give the user a descriptive first and last name, e.g. 'RapidPro Bot'
+  - Add the user to the 'rapidpro_chatbot' group (in the _Roles_ section)
+- Verify everything is set up correctly, by checking that the authorization header to be used by RapidPro when authenticating to IoGT now appears in _Interactive_ > _Interactive RapidPro Channels_.
+
+You can now set up a channel in RapidPro, and add this channel to IoGT so you can start communicating with it.
+
+## Setting up an Interactive Chatbot channel
+1. Find the _Chatbot Authentication Header_ for the chatbot in the IoGT admin panel at _Interactive_ > _Interactive RapidPro Channels_ - displayed at the top of the page.
+2. In your workspace in RapidPro, go to _Settings_ > _Add Channel_.
+3. Select _External Api_.
+4. Fill in the following form fields
+    1. **URN Type**: External identifier
+    2. **Address**: Enter a name identifying your RapidPro server, e.g. my_rapidpro_server
+    3. **Method**: HTTP POST
+    4. **Encoding**: Default Encoding (TODO: Confirm this)
+    5. **Content type**: JSON - application/json
+    6. **Max length**: 6400 (see notes: [1](#note-1), [2](#note-2))
+    7. **Authorization Header Value**: Enter the _Chatbot Authentication Header_ from the IoGT admin panel _Interactive_ > _Interactive RapidPro Channels_, mentioned earlier (include the word 'Bearer' as well as the code)
+    8. **Send URL**: `https://[URL of the IoGT site]/api/interactive/rapidpro-webhook/ ` where `[URL of the IoGT site]` is the URL of your IoGT site, e.g. `rw.goodinternet.org`.
+    9. **Request Body**: `{"id":{{id}}, "text":{{text}}, "to":{{to}}, "to_no_plus":{{to_no_plus}}, "from":{{from}}, "from_no_plus":{{from_no_plus}}, "channel":{{channel}}, "quick_replies":{{quick_replies}}}` (TODO: Check whether we can omit the `to_no_plus` and `from_no_plus`)
+    10. **MT Response check**: ok
+5. Click _Submit_
+6. You will land on the _External API Configuration_ page
+7. Copy the _Received URL_ that is displayed on the page. This URL should look roughly like this: `https://[your RapidPro server]/c/ex/some-uuid-here-7afd839d7123-a95d/receive`
+8. Go back to the IoGT admin panel, _Interactive_ > _Interactive RapidPro Channels_, _Add interactive channel_.
+    1. **DISPLAY NAME**: This is the name that users will see when interacting with the interactive bot.
+    2. **REQUEST URL**: Enter the _Received URL_ from step 7, immediately above.
+
+### Notes
+
+<a id="note-1">**1**</a> On older RapidPro installations the upper limit might only be up to 640.
+
+<a id="note-2">**2**</a> Messages longer than the limit will be split up into multiple parts and will have to be re-joined on the IoGT side, which can cause spaces between words to be lost. Thus, larger limits are better, so we can avoid messages being split as much as possible.
+
+## Allowing users to interact with a Chatbot
+As part of an Interactive page content, you can now add an _Interactive RapidPro Chatbot button_. It has the following form fields:
+
+- **Title**: The title identifying the conversation with the chatbot in the user's inbox.
+- **Trigger string**: The initial message that will be sent to the chatbot, starting the conversation
+- **Channel**: Select the channel you just created.
+
+Upon clicking the page title, the user will be directed to the interactive page (showing the first message from RapidPro).
+
+## Create a service account in IoGT with the management command
+
+This is only an option for those who are operating an instance of IoGT (system administrator, ops team). The management commmand performs the manual steps for creating a service account in IoGT (detailed above) and is provided to automate the process (e.g. when an IoGT site is first created).
+
+The setup command.
+```
+python manage.py sync_rapidpro_bot_user
+```
+
+There is another command that will print the authorization header to be used by RapidPro when authenticating to IoGT.
+```
+python manage.py get_rapidpro_authentication_header_value
+```
+
+This is the same value that appears in the IoGT admin panel under _Chatbot_ > _Chatbot channels_.
