Advanced config

The endpoint must still return the final assistant text in choices[0].message.content.

Advanced mode lets you edit the full request body that Coreply sends. Use it when the built-in provider forms are not enough.

Enable advanced mode

Choose Advanced Mode

In Coreply, open API Provider and choose Advanced Mode.

Fill in the endpoint

Enter the full Request URL. If the endpoint uses bearer auth, fill in Authorization Bearer.

Edit the templates

Update the Body Template and Suggestion Template fields.

The body template uses Mustache. Coreply supplies the following context to the template and the resulting string is the request body.

Current context format

Templates should start from contexts. It contains the structured contexts that Coreply has collected for the current request.

Field	Type	Description
`contexts`	list	Structured context objects. Use this when your backend understands Coreply context objects.
`contextsJson`	string	The same `contexts` value pre-serialized as JSON. Use this when your request body needs a raw JSON array.

Strings inside contexts are plain strings. If you need JSON-safe interpolation inside a string value, use the compatibility fields below or send contexts as structured JSON.

Context objects

Each item in contexts has these top-level fields:

Field	Type	Description
`type`	string	`chat` or `screen`
`profileId`	string	The profile that produced the context
`label`	string	Optional label such as `messages`
`dropRule`	object	Context retention rule metadata
`data`	object	The actual context payload

Chat contexts

When type is chat, data has this shape:

Field	Type	Description
`data.id`	string	Optional chat identifier
`data.title`	string	Optional chat title
`data.turns`	list	Conversation turns in order

Each item in data.turns:

Field	Type	Description
`sender`	string	Optional sender name
`userSent`	boolean	`true` for the user’s turns
`messages`	list	Messages in that turn

Each item in messages:

Field	Type	Description
`body`	string	Message text
`time`	string	Optional timestamp
`quote`	string	Optional quoted text

Screen contexts

When type is screen, data is a text tree:

Field	Type	Description
`data.text`	string	Optional text at this node
`data.children`	list	Optional child nodes with the same shape

Suggestion template

After the API call completes, Coreply reads choices[0].message.content from the JSON response and exposes it to the suggestion template.

Field	Type	Description
`assistantMessage`	string	The raw text returned by the model
`assistantMessageAutoTrimCurrentTyping`	string	`assistantMessage` with `currentTyping` trimmed from the start when it matches
`assistantMessageAutoTrimCurrentTypingTrimmed`	string	Same as above, but trims `currentTypingTrimmed` instead

Show the response as-is

{{assistantMessage}}

Prepend the user’s current typing

{{currentTyping.raw}}{{assistantMessage}}

Compatibility fields

Coreply still exposes the older TypingInfo.contextMap fields for compatibility. Use them when you want to build a plain chat prompt inside the JSON body. They only cover chat history and typing helpers. They do not include screen contexts.

String map fields

Compatibility string fields are exposed as a string map with four variants:

Variant	Description
`{{field.raw}}`	Original unescaped string
`{{field.jsonEscaped}}`	JSON-escaped string
`{{field.regexLiteral}}`	Regex-literal form of the string
`{{field.regexLiteralEscaped}}`	Regex-literal form, then JSON-escaped

In JSON string values, use .jsonEscaped.

Compatibility top-level fields

Field	Type	Description
`currentTyping`	string map	What the user is currently typing
`currentTypingTrimmed`	string map	`currentTyping` without the last incomplete token
`currentTypingLastToken`	string map	The last incomplete token the user is typing
`currentTypingEndsWithSeparator`	boolean	`true` when typing ends with a space or punctuation
`pastMessages`	list	Chat history only, grouped into turns

pastMessages does not include screen contexts. Use contexts if you need them.

The `pastMessages` list

{{#pastMessages}}...{{/pastMessages}} iterates over chat turns from oldest to newest.

Field	Type	Description
`sent`	boolean	`true` if the turn was sent by the user
`received`	boolean	`true` if the turn was received
`sender`	string map	Sender name or role
`messages`	list	Messages inside the turn

Each item in messages:

Field	Type	Description
`content`	string map	Message text
`sent`	boolean	`true` if sent by the user
`received`	boolean	`true` if received
`sender`	string map	Sender name or role
