You can withdraw a pending connection request yourself at any time, directly from The Outreach Platform.
How to withdraw a connection request
Go to LinkedIn
Click My Network in the top navigation
Select Manage (next to "Invitations")
Click the Sent tab
Find the prospect and click Withdraw
Keep in mind: once you withdraw a connection request on LinkedIn, you won't be able to send another one to that person for up to 3 weeks.
Can Spear withdraw requests automatically?
No — withdrawing connection requests must be done manually on LinkedIn. Spear automatically manages pending requests by deleting the 32 oldest ones daily to keep your account within LinkedIn's limits.
