Sym helps developers solve painful access management problems with standard infrastructure tools.
Is your team experiencing:
Sym can help! This quickstart will help you launch a new access flow in under an hour. Your engineers will be able to safely and conveniently gain access to sensitive resources, all with the guardrails you need in place.
If you want to check out a demo, go here!
We're going to walk through setting up a fully custom access control workflow using Slack and Sym. By the end of this tutorial, you'll have the ability to wrap any resource with an API with a fully-configurable request-and-approval flow, using a declaratively provisioned Slack app.
The complete code for this tutorial can be found at @symopsio/sym-custom-strategy-quickstart
.
Users will interact with this Sym Flow
via Slack. Slack connects to the Sym platform, which executes a Flow
that use the Integrations
we are wiring together in this tutorial.
This is what a request will look like.
Sym will send a request for approval to the appropriate users or channel based on your impl.py
.
Finally, upon approval, Sym invokes your custom escalate
method and updates Slack.
To complete this tutorial, you should install Terraform, and make sure you have a working install of Python 3.
The app environment includes everything you need to get a custom workflow up and running. Just configure a few variables in terraform.tfvars
and you're on your way!
Here's all that you'll need to do:
symflow
CLIYou'll need to work with the Sym team to get your organization set up with access to the Sym platform. Once you're onboarded, continue from here.
symflow
CLIThe symflow
CLI is what you use to interact with Sym's control plane.

We'll have to login before we can do anything else. Sym also supports SSO, if your organization has set it up.
$ symflow login
Sym Org: healthy-health
Username: sym-implementer@healthy-health.co
Password: ************
MFA Token: ******
Success! Welcome, Sym Implementer. 🤓
You simply have to take the slug
given to you by the Sym team, and set it in app/terraform.tfvars
.
# app/terraform.tfvars
sym_org_slug = "healthy-health"
Now that you've got symflow
installed, you need to install Sym's Slack app into your workspace.
The easiest place to find this is in the URL you see when you run Slack in your web browser. It will start with a T
, and look something like TABC123
.
This also goes in app/terraform.tfvars
.
# app/terraform.tfvars
slack_workspace_id = "TABC123"
symflow
has a convenient way to provision an instance of Sym's Slack app. This command will generate an install link that you can either use directly, or forward on to your Workspace Administrator.
$ symflow services create --service-type slack --external-id T123ABC
Successfully set up service type slack with external ID TABC123!
Generated an installation link for the Sym Slack app:
https://static.symops.com/slack/install?token=xxx
Please send this URL to an administrator who has permission to install the app. Or, if that's you, we can open it now.
Would you like to open the Slack installation URL in a browser window? [Y/n]:
Once Slack is set up, try launching the Sym app with /sym
in Slack.
You should see a welcome modal like this one, since we haven't set up a Flow
yet:
This Flow
is set up to route access requests to the #sym-requests
channel. You can change this channel in—wait for it—terraform.tfvars
.
Sym will also send any errors that happen during a Run
(due to external failures or config issues) to a configurable error channel. You'll never guess where you can configure this.
# app/terraform.tfvars
flow_vars = {
request_channel = "#sym-requests"
}
You can also change the channel that errors are routed to, which defaults to #sym-errors
.
# app/terraform.tfvars
error_channel = "#sym-errors"
Now that Slack is set up, let's provision your Flow! We've packaged an example AccessStrategy implementation in custom-access-flow/strategy.py
along with all your Sym configurations. This strategy doesn't do anything interesting quite yet, but we can at least make sure all the pipes are connected.
$ export AWS_PROFILE=my-profile
$ cd app
$ terraform init
$ terraform apply
...
Plan: 25 to add, 0 to change, 0 to destroy.
Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.
Enter a value: yes
Apply complete! Resources: 25 added, 0 changed, 0 destroyed.
Positive : By the way, if you plan to provision your flows from a CI pipeline, we've got you covered.
You should be able to make a request now with /sym req
. Once approved, the strategy.py
example AccessStrategy should be invoked, and you'll receive Slack direct messages on escalation and deescalation.
Once you've got your Flow talking to the example AccessStrategy implementation, its time to customize it to do something interesting for your team.
A couple helpful tips:
Sym invokes your AccessStrategy with a target_id
and an Event
. Read more about working with Events
in our Working With Flow Data docs, or check out the full API reference for the Event
class in our SDK docs.
Now that you've configured your custom AccessStrategy implementation, its time to validate that your integration works end-to-end. Double check that your function is properly responding to escalation and de-escalation events and handling error cases!
Here are some next steps to consider:
LogDestinations
.Flow
to require that users be members of a safelist to approve access. flow_vars.approvers
with the safelist of approvers in terraform.tfvars
.hook
annotation on the on_approve
method in impl.py
. This is just one example of what you can do with hooks in the SDK!symflow
CLI to configure user mappings when required.Flow
logic. Maybe change things to allow self-approval only for on-call users?Flow
