+    steps:

+          uri: "telegram:bots?authorizationToken=XXX"

+[source,yaml]
+----
+- from:
+    uri: "timer://tick"
+    parameters:
+      period: "1s"
+    steps:
+      - to:
+          uri: "telegram:bots"
+          parameters:
+            authorizationToken: "XXX"

+      period: "1s"
+    steps:
+      - telegram:
+          type: "bots"
+          authorizationToken: "XXX"
+----
