Screenshot of the Slate partner dashboard: Sign in and your account

Everything you need to get into your Slate dashboard, and back in when something goes wrong.

Slate has two dashboards. You start in the first one.

  • Sandbox is for building and testing. Nothing there touches real money or real customers. Address: partners-sandbox.tryslatehq.com
  • Live is your real program. You can't sign up for it: Slate turns it on for you when you're ready. Address: partners.tryslatehq.com

The two never share anything. A customer, key or setting made in one doesn't appear in the other.

Create your account

You do this once per company. Takes about two minutes.

Open the sign-up page

Go to partners-sandbox.tryslatehq.com/sign-up.

Fill in the form

Every field is required.

The Create your account form, filled in, with the email, name, company name, domain and button numbered
  1. Email: your work email. You'll sign in with it, and your codes go there.
  2. First name and Last name.
  3. Company name: as your customers know it. It shows at the top of your dashboard.
  4. Domain: your company's website, without https:// or www. For example northpinefreight.com.
  5. Create account: sends the form.
The Domain field containing northpine and the message Please enter a valid domain
northpine on its own is not a domain. northpinefreight.com is.

Select Create account

Slate emails you a six character code and opens the Set Password screen. Keep this tab open.

Set your password

Find the code in your email

It arrives within a minute or two. Check spam if you don't see it.

Enter the code and choose a password

The Set Password screen with the code, new password and confirm password filled in, all rules ticked, and the buttons numbered
  1. Code: the six characters from the email, no spaces.
  2. New Password.
  3. The rules: each one turns into a tick when you meet it. You need 8 or more characters, an uppercase letter, a lowercase letter, a number and a symbol.
  4. Confirm Password: type it again.
  5. Next: stays grey until every rule is ticked.
  6. Resend Code: if the email hasn't come, or the code expired. Only the newest code works.

Select Next, then Next again

You'll see Password successfully set. Select Next, type your new password, and select Next again.

Add a second sign-in step (recommended)

The first time you sign in, Slate offers two-step verification. With it on, a stolen password alone can't open your dashboard.

The 2-Factor Setup screen offering an authenticator app or a device option, with a Skip button
  1. Pick a method. Authenticator App works with Google Authenticator, Microsoft Authenticator or Authy: scan the QR code, then type the six digits the app shows. Device dependent uses Face ID, Touch ID or Windows Hello on this computer.
  2. Skip goes straight to your dashboard. Slate will offer it again later.

Your first look

You land on Home in sandbox. The first time, a short welcome tour opens. Select Next to step through it, or the X to close it.

"User could not be found"

Slate doesn't know that email in this dashboard. Usually one of these:

  • A typo. Fix it and select Next.
  • You're on the live address with a sandbox-only account. Use the sandbox address until Slate turns on live.
  • Your company signed up with someone else's email. Ask them to invite you from Team.

The code never arrived

  • Wait two or three minutes, then check spam or junk.
  • Select Resend Code. Only the newest code works.
  • If your company filters email, ask IT to allow mail from tryslatehq.com.

"An organization with this domain already exists"

Someone at your company already signed up. Ask them to invite you from Team.

"Switch to Live Mode" is grey

Live isn't turned on for you yet. Finish the checklist on Home, then select Request production access. See Going live.
