This will be used for a fallback option if no user with the provided username can be found. ``` symphony://chat_with?username=&name=John%20Smith ``` When the app is launched with the above URL, the UI should pop to the root view controller (if necessary) and then automatically go to a 1-1 chat with the user John Smith. * If a 1-1 with the user `john.smith` already exists, all the conversation history is expected to be present. * If a 1-1 conversation with the user `john.smith` doesn't exist yet, a new 1-1 conversation is created. * If there is no such user with the username `john.smith`, the user is directed to a global search on the **People** tab with the search text field pre-populated with the user's full name. {% hint style="info" %} **Note:** The Symphony Messaging URI only supports internal use cases, as the search by username is only possible within the same company. {% endhint %} --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.developers.symphony.com/embedded-modules/symphony-uri/symphony-uri-for-mobile.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
