How to Create an Outreach Sequence
This guide provides best practices for automating outreach efforts by compiling a list of profiles and sending invitations in bulk on LinkedIn. It also offers strategies to save time during the integration process
Extract a LinkedIn Search from an Url
Origin of the List of Contacts
The first step in creating an outreach sequence is performing a search on LinkedIn. Users can filter and select profiles through either the standard LinkedIn search or Sales Navigator, using various filters such as job title, industry, or location to refine their results.
Handling Search URLs
Use the LinkedIn Search API to fetch search results for your users. You can process direct copy-paste URLs from users or enable parameter selection in your app’s UI. Ensure you implement pagination to capture all results and spread requests over time to mimic natural activity.
Compiling & Managing Results
For effective outreach, manage up to 1,000 profiles per day (or 2,500 for Sales Navigator accounts), and space your requests throughout business hours. LinkedIn limits invitations to 200 per week per account, so it’s important to plan your sequences carefully to avoid exceeding these restrictions. You can plan and manage different types of sequences—search, invitations, or messages—based on these limitations.
Planning Your Outreach Sequence
After compiling your contact list, schedule the outreach sequences according to LinkedIn’s limitations. Depending on the type of sequence, such as searches, invitations with InMail, or message templates, adjust the daily limits and distribution accordingly. For example, distribute 30–50 invitations daily at random intervals to stay under the 200-invitations-per-week limit. If you have multiple sequences running, pause or adjust them to stay within limits. Make sure public profile IDs are converted to private IDs before sending out invitations to ensure successful outreach.
Handling API Errors and Using Alternate Accounts
If an API call hits LinkedIn’s limitations (such as users sending invitations simultaneously), manage the error by rescheduling the sequence for another week. Notify users of the delay and adjust accordingly.
Outreach with Multi-Channel Sequences
Connect Accounts and Initiate Outreach
Integrate LinkedIn, WhatsApp, and Other Platforms
Before you can handle chats and messages, you must connect an account of the wanted messaging provider. Discover Unipile’s connection methods in this section. Unipile’s API provides two account connection methods, ensuring that you can seamlessly synchronize accounts for different messaging services. Connecting an account involve authentication to the messaging provider through Unipile’s API.

Hosted auth wizard
Hosted Auth Wizard is the quickest and most straightforward way to connect accounts, as it involves a single API call to generate an temporary link to redirect users to a Unipile’s Hosted auth wizard. The wizard guides users step-by-step, supporting various authentication methods.
Custom authentication
If you want to embed a custom authentication form/wizard in your application, choose the Custom authentication approach. This approach offers the freedom to build a unique and tailored authentication experience that aligns with your application’s specific needs.
However, it’s a more advanced approach that needs more work as it requires implementing specific authentication scenarios like QR Code scanning, 2FA, and One-Time Password by yourself.
Feature available for : LinkedIn, WhatsApp, Instagram, Messenger, Telegram, X (Twitter), IMAP.
For Microsoft Outlook and Gmail Overview, consult this guide.
LinkedIn Integration Focus
The following steps outline the process of integrating LinkedIn into your application using various authentication methods, including username/password and cookies. This guide is designed to help you navigate the LinkedIn API to ensure smooth integration and functionality.
Step 1: Authenticate to LinkedIn
To start, you have two options for LinkedIn authentication:
- With Username/Password
This method requires the LinkedIn username and password to initiate authentication.
2. With Cookies
This method uses existing LinkedIn access tokens, specifically the li_at cookie and the you can get when connected to LinkedIn in your browser. Make a POST request to this Unipile API endpoint or use the appropriate SDK Method.
We strongly recommend collecting the user agent from the browser where the cookie is obtained to prevent account disconnection
Step 2: Handle Checkpoints
After the initial authentication, LinkedIn might require solving checkpoints like 2FA, CAPTCHA, or Phone Register. Use the response from LinkedIn to identify the type of checkpoint.
Step 3 : Solve checkpoints
Solve 2FA and OTP
For each checkpoint type, send a request to solve it. Example for 2FA:
Step 4: Handle Intent Timeout
If the user takes more than 5 minutes to solve the checkpoint, the account will not connect. Ensure you solve checkpoints within the required timeframe to avoid issues.
Step 5: Connect Through a Proxy
If necessary, use a proxy to connect the LinkedIn account. You can specify the proxy settings in the request body.
Getting Started with Hosted Auth Method
1. Add a “Connect an account” button to your product. When clicked, use our Hosted Auth API to generate a unique link and redirect the user to it.
2. Create a database to store connected accounts with fields like: id | user_id | account_type | account_id | status | last_update | created_on.
3. Set up a backend endpoint to receive API calls when users connect their accounts. Store the account_id linked to your internal user_id.
4. Create a landing page to display the connection status. Include a “Reconnect” button that uses the Hosted Auth API with a “reconnect” parameter for any accounts needing reconnection.
5. Set up a webhook in our API to monitor account status changes.
6.Build a backend endpoint to process the webhook and update the account status. For critical statuses like “CREDENTIALS”, prompt users to reconnect via email or the UI.
Google Chrome Extension case
If your app has a browser extension and you want to connect LinkedIn accounts, you can implement background authentication using cookies. When the account disconnects, collect a new cookie and use the ‘reconnect’ method without user action for a seamless experience.
Steps for LinkedIn Cookie Synchronization:
- Collect Data: Gather
li_a,li_at,user_agent,ip(country-based for Unipile), and an identifier for the connected account (parse LinkedIn HTML to get the user ID). - Store Data Regularly: Save collected data to your backend as:
internal_user_id,unipile_account_id,unipile_status,date_last_cookie, etc. - Initial Connection: If
unipile_account_idis empty, use custom authentication to connect the account. - Handle Disconnection: When notified by the webhook, use the ‘reconnect’ function with the last stored cookie and
account_id. - Retry Reconnection: If it fails, retry every hour for 4 hours. If still unsuccessful, send an email prompting the user to reconnect and ensure their extension is configured properly.
